yeah I looked everywhere on the box but nothing on there. ill try both and see which one it is. thanks for your help

Hey Vaughan, how do I know if the ecu came with a 4 bar or 7 bar map sensor? on the website it lists either or

sorry with all the questions, but for the injector dead times on the g4+ its battery voltage/ fuel pressure but on the g4x its battery voltage/ MGP (kpa) do you know a way i can transfer that over? I've gotten alot of the values transferred over but just stuck on the injector dead times.

yeah it'll need a whole new tune but I just wanna get the car running to make sure everything is good with the new built motor.

Hello Everyone, I was hoping to see if anyone has had any luck transferring data from a g4+ to the newer g4X? I recently picked up a g4X for my Evo 5 and was looking to get the car running and fix any possible issues before I take it in to get tuned again. car was tuned on the g4+ 3 years ago but decided to upgrade to a newer ecu.

Hey sorry I never uploaded the log or tune having starting issues on the car now. But for some reason ecu is reading the wideband now with no more errors

Sounds good I’ll post it up in about an hour when I get home

I didn’t wire it up using the CAN connection it’s still on the expansion loom using AN volt 6. I can upload the map with a log file

Hey sorry for all the questions, I installed the X series wideband last night and it was still throwing Lambda 1 Signal error and a AV volt 6 below error low value. I've checked the wiring 3 times and everything seems fine would this possibly a calibration issue? i also just wired it up to the expansion loom for the time being.

Thank you so much for your help. That’s exactly what I needed

Hey so I got a x series wideband and I’m looking at the CAN connector but there’s a couple different options how would I determine which one to get?

sounds good thanks for all your help. ill slap in a x series wideband for now and look into the link can lambda over the winter

I was thinking of doing that over the winter. For now I just wanna drive it and break in all the new parts

I see so would it just be better to go out and get a x series and wire that up?

I just have it wired up to an expansion loom. I’ll double check on which volt I had it rewired to and go from there. As for the ground on the aem wiring diagram it just says black cable to chassis ground should I have it wired up to the loom?
