Hi all,

Just a quick question:

I have an Innovate LC-1 with a DB9 serial out- but my laptop does not have a serial port- I'm using a USB -> SERIAL adapter I bought from Jaycar.

I can get the LM Programmer software to recognise that the LC-1 is connected but it wont show up any data.

The LogWorks software wont recognise the LC-1 at all.

Free air calibration and setup was all done according to instructions.

Anyone else had any dramas/ experience with this?

Cheers

Chris

common issue. those usb to serial adapters are a royal pain in the ass.

sometimes certain brands don't work with different devices but can work with others. its completly random.

check that the drivers are installed and they are the correct ones, check for IRQ conflicts as well.

also check another serial device with the usb -> serial adapter to make sure its working

do you have your laptop plugged into a 12v to 240v inverter? alot of the times those things cause lots of issues especially the cheap ones, try it with the laptop running on battery.

if all fails try another brand usb -> serial

I know i had heaps of issues with the USB cable for my Vipec ECU, as soon as i converted the cable to serial and used a serial port on the car pc all works 100% of the time.

good luck with it

I work with serial adapters all the time.

The best one I've found is a cheap STLabs unit. Can pick them up for about $35.

They've worked with all the PLC Devices I've had to connect to as well as all my alarm panels and access control boxes.

Also work well with my own Haltech.

If you look on some of the Boards in the US people using Datalogit and Innovate stuff found out which USB cables with the electronics in one of the plugs works . Off the top of my head Sewell (sp ?) do one that is supposed to work .

Honestly Lap Tops with serial ports are the way to go IMO and if you only use one for tuning cars they can be quite cheap for what they are through Ebay .

I have a Dell Latitude D610 on the way through Ebay and minus postage will owe me 380 .

Your call , cheers A .

if you are still stuck trying to get it working

see if you can disable all the on board com ports and remove them from windows (right click, un-install)

make sure they are all gone and disabled (if possible, some bios's will let you)

and then install and use the USB dongle one - make sure its un-installed first

so you should have only 1 COM port, which is the USB and see if that works

like the others have said though, USB emulators are hit and miss

depends on the driver, the program and the adapter

best bet like disco said and what i do as well, buy an old dell laptop off ebay with a true serial port

perfect for everything you need for car tuning

the whole reason he is using a usb-serial adapter is because his laptop does not have any onboard com ports

Thanks for all the replies guys, yeah the software is looking for the LC-1 at a COM port, but as Guilt-toy said, i don't have any COM ports.

From what i understand, the drivers with the adapter are supposed to make the USB input 'appear' as a COM port? Does this sound right?

Otherwise I have seen some SERIAL -> PCM CIA adapters that go into the network card slot. I might give that a shot, or buy another laptop.

I also had a quick read of an article on the web that said you can wire a DB9 serial plug into a DB25 com/parallel port and it works?

I'll be the first to admit I'm not great with computers so if this makes sense to someone...! Great!

Cheers

Yes that's right.

That wont help, its only changing the physical socket from DB9 to DB25 - you still have to have RS232 driving it. A parallel port isnt RS232 so you cant make a serial port out of it.

Oh Adrian where would we be without you? Tom mentioned you might be going for a test run with him? Maybe see if you can get the LC-1 to work with the PCM CIA thingo. I dont really want to buy another laptop. U rang before mate, did u get the size of your rad hose?

i have had this problem with USB > serial converters before, and 99% of the time it can be fixed by changing which com port the device is assigned to from device manager (change it to com1 or com2) some programs have issues talking to com8 etc, that they are normally assigned to.

From the device manager window, double click on the USB serial port. click the port settings tab and click advanced. select com port 1 or 2 (it will tell you if they are in use) click ok twice and you should be good to go.

USB> Serial is a pain.

If it's not constant, it will be intermittent.

PCMCIA > Serial is better but can be annoying sometimes too when you knock it due to the tight space in the car. Then some new laptop only take the express pcmcia card :)

By the time you had enough with these connector you will get a cheap old laptop with a serial port just to muck around in the car....or get an ecu with a usb connector.

Yes I think that's ultimately the way to go , when it absolutely has to work use the proper tool for the job .

I've seen early Dell Latitude D400s and D410's going for two hundredish , actually those early critters were very good at using very little battery power which is what you want when out on the road .

The problem is that they may not be so good at playing a DVD movie or hardware intensive games - but the point of all this is tuning an engine management system so a fair bit of folding stuff hangs in the balance if it goes wrong .

Am sure quite a few here have had instances of the lap top lemoning out whilst tuning on the road and then your stuck with whatever settings your EMS feels like remembering .

It could be a long wait for a USB cable/co-operative Lap Top to get it right .

In my experience serial ports and cables either work or they don't , and another serial cable is inexpensive and reasonably easy to get .

A computer head friend of mine keeps telling me that very expensive scientific test equipment nearly always interfaces through serial RS232 hardware .

He also said that is the reason why expensive Business or Desk Top replacement Lap Tops tend to have serial ports where the home entertainment ones don't .

He has less than zero faith in USB and I agree that it often works poorly when you need it most , depends on the application I suppose .

If your car/engine/EMS is worth more to you than 200-250 buy a cheapie serial equipt lap top .

Only way to be sure , cheers A .

Thanks heaps for the help guys, Ill try everything suggested and see how I get on. Worst case scenario t I might have to invest in a cheapo laptop for tuning... Or just buy a gauge for the LC-1 (which would have been a smart idea from the start!)

Cheers all

Chris

silly question possibly but why dont the new aftermarket ecus on the market these days just come with a usb plug so u dont have to use a usb to com adaptor???? wouldnt this stop the problem? I have issues with my laptop and my autronic ecu but everyone elses laptop works fine using the same usb cable which is weird. Try an Aten usb cable i been told they are the best and only $35 or so, i was told to stay clear of Belkin which is sold in most places too.

    • Yeah, thumbsup from me. The distant shot of the bay just looks same-same as before.
    • Dad had a court case drag out with them from 1998 to 2004. He was in a not at fault accident, NRMA were the ones who covered the other person. They tried to blame his neck injuries on the fact he'd had an injury in 1981 on his extreme lower back where he slipped a single disc right near the bottom. Had been all cleared from that injury for years. This accident destroyed his shoulder, and f**ked a heap of discs in his neck, and he still has major problems with it to this day. Sarah's sister while on her L plates had a small Suzuki Alto, she had stopped to give way to an ambulance, and someone changed lanes behind her because there lane was also slowing, and rear ended her at 80km/h. (She had been stopped for a few seconds already too!). Car was completely f**kED. NRMA sent the vehicle around to 3 different workshops as they kept claiming "We believe it can be repaired, and not written off, we just need to find the correct workshop". It took 3 months, and a lot of arguing before they'd concede and wrote it and paid out. About two years later her sister had a Lancer, someone pulled out of a stop sign without stopping (in an 80 zone). Her sister swerved, hit the front of the other persons car (Instead of dead t-boning the drivers door), which ramped her Lancer, and made it roll multiple times down the road. It hit every panel on the way through. Her sister had slid her self out of the car, and remembers the ambos walking to the accident (They'd been sitting at a set of lights just down the road and witnessed it) and they were saying "Well, this ones going to be a fatality, no way you can walk away from that". Well, she did. And then NRMA sent two assessors out to look at the car, both of which wrote it off. They tried to send another assessor out, except a HUGE uproar was raised, and they FINALLY paid it out. That was on a car, that had damage to EVERY panel, you could see from 100m away the whole car was also twisted, roof bowed etc. Nah, we'll try get out of needing to payout on a $10,000 car... Her sister ended up with major shoulder reconstructive surgery being required, and was permanently limited in her ability to do her job as a nurse after that, as she can't (And was told before surgery too this would be guaranteed to happen) regain full strength in that shoulder. However, there was no choice to not have it, as she could barely use her arm, which was her dominant one, and was in near constant major pain. (And she's the type of person that would try and walk off a broken leg!) NRMA did the biggest run around on the personal injury side too for about 18 months, even to the point of trying to put 100% blame of the accident on Sarah's sister, even though the other driver admitted she didn't look, and didn't stop, and was charged by the police. Sarah used to have a Barina insured with them. It was a policy setup, paid all 12 months in advance. At the end of the 12 months, Sarah was living with me, I reviewed the renewal, it clearly stated "If you do nothing, your policy will cease on XYZ date". We did nothing, as we moved her insurance in with all of mine and I was with Shannons. We find out 10 months later, NRMA decided, because he DAD had a car insurance policy at the same address as what Sarah's mailing address was (Garaged address had been changed), that they'd put Sarah's (What should have been non existent policy) onto her Dad's month to month charges on his credit card. We had to jump through hoops, to get a refund. They didn't care that we actually found the letter that said "If you do nothing, your policy will cease" they made us prove we had NON COMPULSORY insurance else where before they'd issue the refund, and after they agreed to the refund, it still took another 6 weeks and 3 more phone calls for them to actually process it. They also had two insurance claims from storm damage, and they were an absolute cluster to get resolved as well (one vehicle, one house). Some how, up until about 3 years ago, her parents were still loyal to NRMA too, and we were like "How the hell are you so loyal to staying with them, when other places are so much cheaper, and they've f**ked you over every time you've ever had to make a claim?"
    • I got the four AN10 fitting welded up to the cam covers and started up making the head to sump breather/drain lines. The front passenger side cover I used a 45 up top and a 90 at the bottom into the stock VCT head drain spot (3/4" BPST to AN10 adapter) thats unused on the RB25DET NEO with some speedflow flame shield to protect it from the manifolds heat.   back passenger side was a 90 up top with some flame shield and 45 at the sump end. The rear drivers is 45 at both ends   the front drivers fitting is capped off for now but ready to go if i want to try moving the breathers around. I was told by the fabricator to leave all the welds raw for now to make sure there are no pin hole leaks. A lot of cleaning up, re bundling looms and degreasing to go as well as final assembly on the cam cover baffles. The first real test will be 28th March at a Circuit event. added complexity and more spots for leaks but overall looks relatively neat imo
    • Yeah i think the dash needs to come out. To get the loom or maybe just climate control and radio cluster. My mirrors are done i think the motors don’t work so well after flood haha i need the ac fan, you said you wanted to keep it for your 31 and interior loom not including boot. The wiper motor. I’m not sure how good the window surrounds are on the exterior on the pintara.  I will message you to get your bank details shortly 
    • Just another barrier put up to stop cars being modified. When we're all driving Chinese sewing machines, you won't want to modify it anyway, and you'll likely already have slashed your wrists and be locked up in a padded room for your own protection.
