Nistune Forums

i didnt get the original chips back either time i had them install nistune in either of the ecu's. was i supposed to i wonder? i suppose i can call and see if they kept it or if it is even re useable. i could attempt to transfer, but i sure would feel better having a pro do it. will send you an emai...

Sadly the known good Ecu, with nistune transferred to it , is back to the same symptoms. Mismatched banks and increased misfire when warming up. Im open to suggestions at this point but at least we know closer to what the problem has been. and good to know that both my stock ECU's ($$) are ok haha. ...

been awhile but im back! i did the clutch job and got carried away with a bunch of restoration. i just got the ecu's back today from conzeptz. 20210430_153410_compress14.jpg will try to swap it in this weekend. before i do, thought i should ask. im still stock everything, do i have to do anything wi...

they are both the same jdm ecu 23710 41p13 a18-000 m05 20210104_090857_compress73.jpg thank for the advice that makes sense. i will be doing a clutch upgrade when i get time, so while its down i will get the ecu's taken care of. ive been driving it for a couple days now its doing good so far. still ...

pretty stoked after todays test drive. its driving like it always should have !!! burning clean in every gear every pull, both banks. at very first start up it was around 15 on one side, 14.5 on other, changed up in seconds and stayed 13.6 (ish) on both banks through rest of heat cycle. not sure how...

well this car is making a fool out of me yet again. was prepping to do the noid and compression tests, thought for kicks i would put the un modded ecu in again while doing the warm up. and just my luck the wb readings are spot on matching... there is still a slight rumble as it got warmer, but im am...

just touching base here. no fix yet. setup is still stock ecu and injectors, with same symptoms. i finally got some garage time again, so i went back through all the wiring (even though everything under the hood is new.) all continuity's to ecu are good, no shorts to ground, all proper battery volta...

looks like i can rule out the ecm / nistune board. with stock injectors / tune, it performed very similar to the same problems with larger injectors. mismatched banks during warmup...one side spot on stoic and other rich then snap closer to each other when warmer...then they flip flop and other side...

OK sorry for the delay we've had a relentless heat wave and I've been on mandatory overtime. I will get these deutchworks 370 cc installed with stock maps and see what happens.

heres the base file with only changes: LAT 850, TIM 448

the engine died from rpm surging so low, though it was running fine from this tune previously.

with most recent recommended settings the engine was very hard starting then it started surging very high and low idle trying to die out and recover, i did log for a short time but it was so rich in the high 9's so i shut it off. i reverted to previous tune log (most recent forum upload) and the ext...

my apologies i thought i made it clear with the fuel pressure gauge pics, another forum member pointed out my fuel pressure regulator settings were too high at idle, so i adjusted it while using the snapon vacuum tester and nistune "fuel pump relay active" test function. since its running ...

hopefully you can see both wideband on this log as i see them fine on my end. i loaded and uploaded to ecu the file you stated with the lat. and tim changes only. still same issues super rich and mismatched. at temp it just struggles so bad to keep a 14.7 and still the random misfire. i did also try...

fpr is changed, vacuum and ambient pressure are more correct now. i havent been able to test boost yet. didnt seem to help overfueling issues. i will grab the laptop and post the tune you recommended and log from it.
