[sleeper3000]

i'm new to this fourm site. i've had my 91 vr-4 for about 8 months now and am looking into doing some mods to it. i've been looking into the ultimate as the piggy-back system, but i would like to go speed density.

so what all would i need to buy to get it done? and i've read the thread some and saw someone say a compatible wideband o2 sensor for tuning. is the aem uego wideband a compatible o2 sensor?

thanks for any help

Nobody as far as I know has played with either maps.

It doesn't work half as good as you'd think.

It goes strictly off vehicle speed... Your better off using the A/F Target @ WOT. The vehicle speed based just tottaly screwed stuff up from when I've played with it.

Coolant Temp map is good if you need to enrich on startup, but the best solution is just to enable the A/F Target again.

ok i bought the main unit and boomslang harness and boost sensor and harness and a/f sensor harness and injector adapter and i have a aem uego a/f controller. so i guess i just splice the a/f greddy harness into the signal wire on the aem wideband. but what are the 1k and 4k resistors for? and where can i get a gm iat? and i'm guessing i'm suppose to ask for a gm iat for the stealth from the dealer? or does it not matter?

sorry for all the newb questions. i was gonna use the aem ems. but this pretty much does the same thing. but with the aem all was needed was the system and map sensor and uego a/f sensor for tuning. and greddy seems to need alot more parts.

thanks for all the help

Yes. Just match the white signal wire with the white wire on the harness.

Read post 21 Here. Actually almost everything you'll need to know is in this thread. Search it when you have questions.

The Dealer will be confused, heck, my local dealer is confused when I ask for parts that were originally on the car..... Post #7 in this one has a link and part numbers.
IAT sensors?

You are welcome.


Ok, so now that I did my good deed today, has anyone had issues with really erratic or jagged signals on their EMU datalogger? I've been checking my grounds and that doesn't seem to be the problem, but I'll have to do some more checking. I'm getting it on Engine Speed, Throttle Position, my Wideband and occasionally on my Boost. I found Trevor's fix for the boost signal by using a surge tank, but I was sorta at a loss on the others. I'm not getting any fluctuations on my HHH Datalogger or gauges, but I didn't know if the EMU was just reading them so fast it was picking up stuff the others couldn't.

Suggestions?

Thanks,
Blake

Remove the brake booster nipple on the plenum, throw the Greddy pressure sensor in that hole. Youll need a Brass T, and a coupler as well to hook brake and clutch boosteres up on the drivers side of the plenum. I do it on EVERY car I do an EMU in. Doesn't get spiky at all.

What WB02?

[waffleguy]

I'll try moving my Boost line over to that nipple.

I have an AEM UEGO. What has me sorta confused is that my engine speed is also mildly spiky. I'm going to make my own engine bay grounding kit to see if that helps, but I don't know how else to ground the EMU outside of my boomslang.

Put it where the nipple went :P

what IGN input are you using?

[waffleguy]

I don't understand. The IGN source for the EMU? I figured that was in my boomslang somewhere. I don't know what that would actually be, I'd have to trace the wires.

Do I have other options?
