Hey, I really Really need some help to get my car running well enough to get it to the tune shop!

My setup is RB20DET, HKS 2530, Power FC, RX7 460cc Red top injectors, Z32 AFM, Walbro 255HP Fuel pump! And the normal stuff, FM Intercooler, 3" Exhaust, HKS pod, HKS BOV!

What injectors % should i be running and air flow %???? Ive tried trimming the map down as it seems to be too rich! but still the idle is up and down and it just isnt right!

Could someone check on their car with a simpair setup! Any help would be much appreciated as my babys been off the road for 6 months now and finnally everythings modified ready to go now!

Thanks

- Luke!

choose z32 80mm afm in the airflow setting menu and leave at 100% air flow......u can pull abit out the injectors..... had my car running on 94% with gtr injectors to get it to the workshop....was running like a hairy goat. Other option is to use ur NRMA road service if you have and arragnge a tow truck......helped me out once or twice.

Let the tuner worry about the idle....thats what your paying him for.

Thanks for your reply, i have changed it to Z32 AFM, also the tuner is 4 hours drive away, so as you can imagine i wanna get the AF ratio as close as i can, so i dont foul up or melt plugs on the drive there, it wouldnt be fun changing the plugs on the side of the road...:rofl:

The PFC will be in closed loop at normal temperature idle, so if the idle speed is jumping around it's not the tune. Usual problem is vacuum leak. So triple check all of the hoses.

Getting a modified car to idle is sometimes harder than getting power out of it. After you have checked all of the connections I strongly suggest you forget about tuning the idle and move on . The PFC will also run closed loop for cruise, so it will get the A/F ratios OK for that. Check how it runs on light throttle, it may take a few minutes to learn. Thne a 4 hour drive should be a doddle, just don't do it in peak hour (leave home at 2 am) and don't get out of cruise mode (resist the temptation).

Hope that helps:cheers:

same set up except for Q45 AFM ... i run mine at 50%  

200Kw here they come !!  

good luck :D

Hey, Does that mean you have 460cc Rx7 injectors?

If so is there any chance you could check out what the injector % is set to? and the pulse rate of the injectors...thanks!

As far as i know S5 RX7 injectors are actually 550cc ... not 100% sure tho

and they are set at 50% duty.. now the column next to it is set at 0.00ms through all 6.

hope that helps

      My BMW E39 528i touring

      By PranK · Posted

      So, I've been a little busy on this car. I replaced the bonnet struts which is always satisfying but very confusing that nobody else on the planet seems to do this. Its just my routine first thing I do on any car I buy. The boot struts for both the tailgate and the separately opening glass window was a bastard. And, I found a fair bit of rust in the strut cavity. I filled it with rust converter and cleaned up as much of the dirt as I could. There was so much dirt. One piece of the trim was barely hanging on and so I've left it off. I'll try to get a replacement. You can see how disgusting and dirty it all was in this thread; I had to remove the little clips that hold the struts on the ball. The ones I took off had no clips and it was impossible to get them on with them in place. Fingers crossed they stay put. So, I turned my attention to the headlights, they were in a bad way and likely would stop rego. I took the headlights out and found the adjusters were all just loose. So, I fixed those and unclipped the lenses to clean them up. Couldn't believe how easy it was to take all this apart compared to the E90.   I also cleaned up the stockies which was awesome, these are super cool with lug nut covers. They're in good nic but the tyres are shot. I was going to use these for rego but in the end got a fresh pair of rubber for the 17's on the front of the car instead. The front bar of this car is from a late(r) model one. I don't think it's quite LCI but who knows. I'll need to find out. Anyway, the bar was missing the fog lights and the wiring and plugs were for the original ones so I got new plugs and some cheap fogs. I wasn't sure if missing original equipment would hamper my blue slip attempts. Had a couple of these little fellas helping out. But not Ben who got stuck behind the pool heater .... How embarressment.  I ordered new speed sensors for all corners because I knew one was out. I just got cheapies and will replace them with Bosch items when I can find Bosch items. Again, this was just for rego. Alas, it seems the blue speed sensors are not the same as the grey ones. Back they went and replacements ordered. In the end, with my new scan tool, it was just rear left that was shot. Replaced it and cleared the codes. All good now. Lastly, my aux (thermo) fan is being a bit odd. Its powering up at strange times and NOT powering up when I think it should (100C). While this can be caused by a few things, the most likely (for me) is the ambient temp sensor. Given mine reads -40.0C regardless of the temp, I figured it would be good to replace it. In the end, the sensor wiring was abysmal with (terrible) attempts made by somebody to fix it.   I fixed this all up but the sensor is only attached using pins into the wires. The plug is not there. Despite trying and trying to connect it securely it wouldn't work so a replacement sensor and plug is on the way. Oh, I also ordered a replacement piece of trim for the part missing here at the bottom. Ordered from Latvia for $70 delivered. I took a bit of a leap of faith because I didn't have the exact part number and, as usual, there were eleventy billion pieces of trim that looked to fit. Nailed it. Well, its not totally perfect but I think its more a 28 y/o car problem than a trim problem. And, as of today ..... I have bought the workshop manuals 2nd hand off a guy in tassie. 1000+ pages of E39 goodness, hopefully it helps me with the fan. I also have a new temp switch on the way incase its the problem. Stoked.

      I don't even know that you want an M2 Competition as a track car. My rule for a track car is only risk as much as you're willing to completely total out. Clean stock C5 Z06 Corvettes out here are cheap. Buying someone else's already ruined track car is even cheaper. Maybe I'm just not that good a driver but even a Fiesta ST on the Nordschleife felt like as much car as I could realistically handle.

      Mistakes were made, my R34 Story

      I've already gone over the cam. A new one is going in. An old one is coming out! The new one is smaller, with less overlap. It has way more lift, but it will be more mild mannered (hopefully, probably very minorly) I'm also measuring for two more mufflers, with the goal of having four mufflers in my car. But that probably will be done by an exhaust shop in a drive in, measure, buy parts, install parts later kind of deal.

      Mine is not even a GTR and I've been resisting the urge to make it a power monster for the last 25 years. And as a consequence, I have driven it to work nearly every day across that span of time.
