I have a 2000 honda prelude that just had the motor rebuilt and a turbo kit put on. It was obd2-obd1 converted with a p06 ecu. Now the car had 1000cc injectors on it and no resistors. At the dyno they tried to tune it and it definitely burnt some stuff out. It fryed their tuning ecu twice. they swapped injectors to a different pair and it still does the same thing. The car will run for like 3 seconds and than just shut off. While frying an ecu! any suggestions on what could be causing this or just somewhere i can start?

If you are running 1000cc injectors and no resistor box...there is your problem right there.

we put resistors on after it fryed the ecu and tried a new set of injectors with resistors and it fried the ecu again ?

Sounds like a wiring issue... Go over your wiring.
Also, double check all of your 2 wire plugs such as intake air temperature on your engine harness...

sounds like maybe you wired the resistor box wrong? What part is frying? I bet it is the little board that sticks up off the main baord... or near it... The injector driver.

the ecu is frying after a couple minutes of running... there is not resistor box my tuner used just regular resistors would that be the problem maybe ?

JaredKaragen

possibly... those little buggers are small wattage resistors... that could cause them to just short when they burn...

use a resistor box out of an 80's honda and you will be pleased in my opinion.

The resistors you should be using if you buy individual ones are big, rectangular and are made out of something close to porcelin if it isn't that. Kinda glassy... anyways, if they are the wrong type, that might be your problem.

Take some Hi-res pics for me, not fuzzy either of the board from top, bottom and angle so you can see the parts of the injector driver (thin rectangular boards (2 or 3 of them close to each other) near an inch tall, and close to the ECU's connector to the harness. Either post em up or email to me @gmail.com

I will help you figure out what is frying on the ECU, then trace it to a sensor to help you Electronics ain't rocket science... Rockets are!

Tis the only thinkg I think of.

ok i will on monday when i get the car back from the shop
