SECURITY

just found my first post for anyone interested: viewtopic.php?f=3&t=842

it was the TPS idle switch. if you read my last post the car it was originally installed in is now a donor. will the same ECU work in my new car?

thanks for asking the right questions Dave, i have a better understand of which angle i should have tackled the problem from. the wiring loom of an auto i had to modify the wiring to suit the ECU to make it idle which one of your suppliers in sydney fixed. but there possibly could be an issue that im unaware of. the problem started 7 or 8 months after getting it running, when sent back to vi-pec i was told it was the MOSFET chip that popped because of something feeding back into the ECU. after the 2nd time it was returned they also said they would install an external wiring solution if it happens again but instead upgraded the main board the 3rd time and did nothing externally to protect it. software and firmware always up to date and had a dedicated long-battery life laptop for quick adjustment or experimenting with e85 (there were no fuel sensors available back when vi-pec launched). i went through the process to clear defects through the IM230 emissions test with a built rb2530, gcg hiflow, 740cc inj, greddy plenum and all other standard emissions gear and passed with 2 (shagged) stock cats, then started testing in full track trim - but the motor was replaced with a spare rb25det after i couldnt reduce n0x enough without having either HC or CO go up using a catco 3.5" cat, i scraped by with the rb25 no problems. im still using the standard heat shield on the gcg hiflow and there are no signs of heat damage to other wiring that is much closer than the loom. the loom itself is in good shape (sell-able) but from an auto. skyline1 has been parked for around 1.5yrs and has only run if jump-started and taken for a quick burn down the road and a track day where it had to be jump started every time it was turned off. ive started stripping the it because i could no longer afford to renew the registration on problem cars in the mid of the construction bust during the GFC. it is now the donor for skyline2 and mates needing parts. skyline1 = 1993 r33 GTS-t owned for 10 years, all work on this car done in my driveway, auto converted to quick shift then to manual, looks like a drift pig's whore. skyline2 = 1995 r33 GTS-t owned for 6 months, manual. the situation now is skyline2 is inheriting the intake and turbo and then updating the engineer certificate with emissions but i have been dreading the thought of going through the same fate if i swap over the vi-pec. its cleaner and i will burn it before confusion convinces me not to re-register it. soz if this sounds like a sob story, the reality is my car gives me an opportunity to slow my mind.

and im left with my junk in my hand and out of wallet almost 2k with a useless car. thanks vi-pec.

have you considered comparing how another ECU reacts in the same situation? ive seen other posts with the same problem as mine, all (including myself) going back to known working ECU without encountering the problem until the vi-pec gets plugged back in. i regret purchasing my vi-pec. i haven't enjoyed my car at all since purchasing it.

is this issue going to get put in the gts/gtr known issues section of the install manual? would be helpful if it was updated there rather than having to check the forums every few months for a permanent fix.
