Car runs after a year of working on it, first time with Chromed ECU

Finally screwed up enough courage to start playing with EcuFlash and EvoScan on my car. Surprisingly, everything in both programs seems to be working on the first try. Uploaded a tweaked version of the default Chrome V2 ROM file. Only things done so far are to put in the numbers for the Evo MAF and larger injectors. Car starts and idles (kinda). Looking at EvoScan, my NB02's are cycling. One sits close to 0, the other sits at 0.9+. Time to let it idle long enough to get the low fuel trims to show up in Evoscan, I guess. Have to go through GregE's procedure for setting the idle.

Win!!

congrats

Wait, i just re-read that... If they don't move, they aren't cycling. If they sit opposite locked like that, I'd suspect O2 sensor pins are backwards on your adapter harness.

I wondered about that also but assumed that was in open loop or something (during a pull).

You are probably right though, wasn't there a problem with some harnesses having them swapped?

I'll have to look into that and check the sensor wiring. They change values when I rev the engine though.

here's Another one!

Not the full Chrome™ you americans have available though (euro ecu here). Greg fixed a file for me still to change the important settings and it works. (also thanks to blackstealth for disabling the euro immobilizer)

anyways, I did my first long drive with flashed ecu today. Also just changed the evo maf settings and injectors. Ran fine. Idles nice.

died once while idling at traffic lights, got really scared I was going to get stranded but just cranked it again and it ran fine the rest of the day. Think that had to do with my battery being shit though and nothing with the tune(or lack of).

I havn't hooked up my innovate o2 yet though which I really should I know(don't burn me :) )

maybe I should look in to fine tuning the idle thingy too. Not that I think it needs cause it seems to idle fine to me. Need to hook up the o2 sensor to know for sure though.

I don't have my WB02 wired into the ECU yet either. The exhaust has a large leak in it currently. When I put on the aftermarket front and rear headers, the angles and mountings changed some, and the front precat housing is about an inch short of mating up to the downpipe. I have a smaller section of pipe stuffed inside to bridge the gap, but its nowhere near airtight, and the WB02 is downstream from that. Shoot, maybe that's why the NB02's aren't looking right. The rear is probably accurate, but the front is probably seeing air contamination. And checking my logs, it is the front O2 that's sitting at 0.039 most of the time. Ah well, after an oil and filter change, I'm just going to have to see if it'll drive around the block without dying too much. Then I need to drive it about 30 min. away to a friends house where we can fab the new front precat eliminator housing and seal up the exhaust.

Ah yep. That'll cause that issue too.

What else had to be done to disable the immobilizer besides switching off the periphery?
