Ok.....:Just an update, I replaced IC19 twice.
Also RM6 was replaced.
Still CEL.
BUT I did take it across town to try in someones car I was tuning. PASSED!
Drove back across town, ECU knocked around in boot. Back into my car and SOLID CEL, datalogs fine, no codes. But stuck in diagnostic mode.......
I think next trick is to remove J1 and install J4, see if it's stuck in diagnostic.
If so i'll remove the 28 pin socket.
HiHi,
car Accord type-r 2001. ecu p28+chip, after 1 year perfect work, blinking cel. But car run great. In another p28+ this chip all fine. Bad 74hc373? (In video 4000rpm boostgenerator for dragstart, car is NA)
bad ecu p28 after 1 year perfect work - YouTube
Hi..In different car, chip without launch, all repeats(civic b20b allstock)
CEL blink like injector pulse, on full throttle no blinking
hi,
my eg can start as normal, but after start the idling rpm intermittent up and down, can felt some jerk also when change gear during drive,fuel consumption high,got black smoke. Foreman did help to put jumper check error with controller, but no error code found. He said mainly MAP sensor or ECU. I do replace with 2nd hand MAP sensor but the problem still remain. Due to no have offline ecu to test, are there any way to narrow down the problem?
ps:my english not good, hope your can get my mean.TQVM.
Just replace the map sensor. Does not require reset unless there error code stuck.Yup, my is std engine and ecu...I give wrong info, my is eh5 year 95.
I will check the ecu tomorrow..i also wanna find the second unit map sensor and test again..thanks ya.
Actually I new with all of this, when the third foremen told me high potential is that two item bad only I start to search online.
Do I need to do ecu reset when replace the map sensor?coz the foremen ask me jz install and see got recover or not when I found the map sensor, but I got read some write need to do after troubleshooting.
