So who wants their ECU's "Chromed"?

I would confirm your patch harness is correct for the maf signal. It sounds like your maf is unplugged.

The exact codes for the MAF are P0110 Intake Air Temperature Circut 1 AND P0100 Mass or Volume airflow

The harness was tested prior to being shipped to me. I purchased it from 99VR4

You're still running a stock ECU...

Please post the list of codes. Have you matched the periphery setup that Aaron posted?

I would still suspect the harness. Either your ECU adaptor or the MAF connector itself.

All 4 oxygen sensor heater circuits, EVAP purge solenoids, EGR, MFR controlled air and fuel metering and Intake air temp and mass air flow sensor codes as well. 11 codes all together..lol on top of that I drove the car 100 miles highway and got crap gas mileage..no wonder...The evap and EGR stuff I can disable on ecu flash..what should I do about the o2 heater circuits and MAF codes?

You need to make sure all the periphery bits match what I have posted a few pages back. If they do not, and the car is not a 98 or 99, it will NOT run properly.

Greg,

You should copy my periphery post, and paste it in the first post of this thread. Make it easier for people to find.

Yeah I followed what aaron had and my sl ecu and evo maf run top notch. Getting great gas mileage and I'm only doing city driving. Finally figured out what was wrong with my sd datalogger(I didn't push it in all the way lol) once I get my wideband I'm going to be test this thing out.

Yeah you're right.

I need to get this figured out so I can release V2 and avoid this confusion. My adventure at the track really distracted me from working on this. What's your schedule like this week? I'm going to poke at things one at a time till we get your car running CE-less without touching the peripherys.

I'm pretty much free the whole week.

Can someone tell me what the "golden" setup would be for a 94 VR-4? New 99 VR-4 ECU and Tactrix 2.0 cable? Is that it? Any other adapters?
