Yes, the proefi is reading the MAP sensor.

 

If your current ECU is tuned for different injectors vs stock then its obviously going to run like crap with a new ECU.

 

But the proefi is controlling the injectors. The factory ecu was flashed for 390cc injectors that were in the car with the previous turbonetics kit. So, with the proefi, would it matter if my stock ecu was flashed or not? The proefi was tuned with the factory flashed ecu in the car.

 

Oh yeah, shoot, sorry. No it would not matter. When you say drives like crap - that should only be at idle. The proEFI idle control will be fighting with the stock ECU. That would be the only issue as throttle fluctuates to compensate for ignition timing that is not responding (to the stock ECU since its in proEFI control only).

You may want to consult UpRev guys and see what they think of the new unit and ensure it is (a) compatible and (b) if one of their flashes can improve the issues. I think you will want to reflash the new ECU anyway because you want NATS reset, your own car's VIN etc, right?

When you swapped out ECU's did all the pins in the connector look ok?

EDIT: So the FSM says if you get the P0605 code twice, the ECM is dead. you need a new one!

 

So, I just let the car sit with the battery disconnected for 2 hours. I plugged the new(used) ECU I bought in and left the throttle under the car's control. The car started up and idled at ~1500rpms. I drive it, just lightly pressing the throttle, I made it a mile before the throttle cut out. When this happened the check engine light popped on. So, I then switched it to the proefi controlling the throttle. It started up and idled at ~1500rpms. I drove around and I can make pulls in the car. However, after driving the idle would "hang-up", right around ~2300rpms. But if I would slow the car with it in gear, I could bring the idle down. It's like the throttle body is hanging open slightly.

I read the codes the new(used) ECU was throwing and it had NATs, evap, cam and throttle codes. All those I expect. However, it also had the p0605 code...

So, that means that my factory ECU is bad. And that I bought another bad ECU. I suppose that is possible. Or that something is killing the ECUs, right?

When my throttle cuts out and the car, I assume goes into limp mode, this only happens when the p0605 code shows up. So, what would cause this code? It happens with two ECUs.

The pins look fine. I have looked at them several times. I don't really mind the nats codes. However, I'm curious if the p0605 code is something that could be turned off. Does anyone know if that is possible with uprev?

I'm also going to talk to Jason at proefi and ask him about the throttle hanging when proefi is controlling the throttle. If I can get that fixed I can drive and enjoy the car. Or if I can get the p0605 code disabled, i could drive and enjoy the car.

 

I would buy another used TB and give that a shot first. You sure no bent pins or water in the harness, right?

 

I'm pretty positive that there are no bent pins. I can get another TB.

Any idea if that p0605 code can be disabled via uprev?

 

I would say it is exceedingly rare for one ECU to go bad. For two with the same code - no way. I don't recall ever seeing the P0605 as an option to disable when I had UpRev. It is just not a code that comes up that often. You would have to check with UpRev and they may even be able to add it to the software by request, but...

It has to be a wiring short or bent pin in the harness.

 

Just a quick update. I took the car to ProEFI and Jason was able to adjust the electronic throttle control setting to get it to work. I have been driving and enjoying the car. It is pulling hard.

I'm not sure what is causing the p0605 code. But with ProEFI controlling the throttle it doesn't matter much. I assume it is a wiring issue.

Anyways here is a quick video of the car. https://www.youtube.com/watch?v=OplZ...ature=youtu.be
