Chrome ECU - Front bank stuck rich

That log is all jacked up.

I can only think of a couple things that could be the issue with the readings, but they do not solve all of the issues.

Going to a zero reading could be wiring, but match that with the constant 0.1**** on the rear says no. ECU?

Odd that the wb is now going lean as it compensates, and the nb are polar opposites f to r. My f/r o2 feedbacks were always close.

You might eliminate an issue with the injectors, and swap the 360's back in to scratch them off the list. If all goes back to normal you have your culprit, if not you can eliminate them out of your diagnostics questions.

Losing ideas here...

Yeah, I'm all sorts of confused with what the hell is going on here. Especially since the car ran fine until I swapped in injectors and turbo's. No wiring was touched.

I agree with swapping in the old 360's and I'll be doing that tomorrow and will update.

I have been reading a lot where people have had all sorts of issues with idle on EVO and these Lucas 550cc Injectors. Seems to be an issue with our ECU compensating for the injector deadtime and pulse width of these injectors.

Swapped the injectors back to the stock 360cc and everything is running fine. Both O2 Cycling as they should, no more rich bank, etc. So I just have to keep the boost down until I can get more fuel.

So now my question is do I send off my 550cc injectors to like Injector Rehab to have them looked at or just ditch them and try to find some other ones??

I'd go for a set of evo 560's instead they are cheap, readily available and proven to work very well with chrome ecu's. Bought my set cleaned and flow matched from the guy on 3SI that has been selling these sets for years.

I saw a bunch of threads in regards to the evo 560's regarding people having issues getting the car to idle properly. I'm guessing it was before Chrome and the ability to adjust deadtime.

Do you have the guys username or a thread you can point me to for the injectors?

I bought mine from this guy:

Unfortunate you had to go through all that you did, but congratz on finding the issue. I'll have to look back at my logs with the DW's and see if they were doing similar at first. (I don't beieve so). I had one hell of a time figuring out the offsets, and finally ditched them at a loss.

I pinged him on the other site to see what he's got. He hasn't been online in a couple months so not sure if busy or not doing it anymore..

Coop - this is not normal so something is going on with them. I had Adam on Facebook for like an hour going over things and messing with the injectory latencies and the one bank would just not cycle. So there is something up with the injector/s on that bank causing the issues. I am glad the 360's are running in it but that means I have to wait again before pushing the new turbos.... :(

I use the pte 1000s great inj.

I bought a set of 1000cc Bosch EV14 high impedance injectors from NZefi.com, best thing I've bought for the car!.

They come with the EV1 connector and spacers so straight fit (apart from deleting the resistor pack), well worth the investment..
