Hi all

I am on of the only people in the NT that has a greddy emu. No one has experience with them here so does anyone have base Airflow maps for the Greddy pressure sensor, or do i need to collect the data on a dyno like this http://www.skylinesaustralia.com/forums/ma...p;hl=greddy+emu thread suggests.

I havent been able to drive my car for a while, so if anyone can help it would be great.

My car is:

1992 r32 GTS-t Auto - no mods

Thanks in Advance

Greg

(Also i am having issues with the car shifting from 850 - 1250 rpm when idling and the car running too rich, Do i just need a tune?)

If your maps are all at 0 adjustments then you shouldnt have a problem. download and run the file below, its got 0 adjustments and is set up for your rb20. as long as you've wired in the EMU right it should work 100%. I've also set up data logging so you can look at all of the right parameters when diagnosing problems.

Cheers, i was beginning to think no one used the emu

I'll see how it goes, i had trouble wiring it up initially and had to take it to one of the tuners here, apparently the injector connections were back to front someone had messed with the factory computer loom. He said that all of the setting were set to zero and hence i should be able to drive it around,

However....

Right now when you depress the accelerator there is a delay before the engine kicks in and at idle it pulses from 850 to 1250 rpm.

Furthermore once when i was driving it after it was installed, if i depressed the accelerator the car spluttered and sounded like it was going to stall, i then pulled over and restarted and it was fine?

Once again Thanks for your response, i appreciate it!

i used an emu for around a year, its a good piece of kit but it can definitely be a headache if not wired in properly. check if the map i put up fixes your problem, if not its possible its a wiring issue or even your jumper settings on the board of the EMU are wrong. also if it doesnt help i'd need a bit more info on whats happening to be able to help you out.

do you know how to read a data log properly to find faults?

Hi

I personally have not interfaced the the emu, i am a little worried about stuffing up my engine. So on Tuesday i am taking it to a tuner to have a look at it however since he has not had experience with the greddy emanage ultimate, i have to find all this stuff out myself.

So, so far i need to:

Open your file and update the emu,

Check the wiring and jumper settings,

Use the Data logger to find issues,

Most tuners in the territory are used to powerfc's, haltech's or Wolf3D's and since i dont know how to tune and have an automatic, i have to decypher the emu for the tuner i use.

Thanks,

Greg

yeah, all of my tuning was vs. psi.

plug in the sensor, set up the OPTION 1 or OPTION 2 (the 2 expansion ports on the front) to whichever the sensor is plugged into, plumb it into your plenum then off you go. its all in the manual.

i actually sold off all of my emanage stuff a few weeks ago including the pressure sensor and plug to input 5v from an A/F gauge.

you need to get yourself a laptop with the manage software and have a play with it yourself, especially when you're the one that is doing the research for your tuner. by the time i was getting someone to tune my car the first time i was explaining the features and helping with the tune. also helps if you have a minor problem and all it takes is a few clicks of the mouse to sort out.

Hi,

What unit do i need to use to utilise the pressure sensor?

Data Sampling Map

Do i use, Throttle Position, Airflow Hotwire, Greddy Pressure sensor, Relative Pressure or Charge efficiency.

Then i need to sample the data, Copy the data then paste that to airflow output map?

Is That correct?

Cheers

Greg

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
