Question Wondering

Would it make since to have another ECU programmed to run in my truck? Just to make sure it is performing correctly since the one I have is out of a unknow truck. It's working fine best I can tell except for the knock senor.

I also have noticed when I crank it up the check engine light blinks really fant until it sets the P0332 code. I have been wondering if this may be a ECU issue.
The truck hasn't ran bad yet due to this code but I just don't like having it set all the time.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: Wondering

I know some guys that had a spare ecm, but when they did the math, it ended up cheaper just to have 1 ecm and a copy of HP Tuners.

The idea was to have 2 seperate tunes, and a 10 minute swap in the pit-lane would have you on the "hot" tune, which in this case was a nitrous tune. I think that idea lasted like 2 weeks. That ECM now sits in the spare's bin, and they just reflash the ECM as needed in pit-lane.

Obviously its a slightly different situation, but that was their move. In direct reference to your question, I'm not sure it would benefit you at all. The only way another ecm would help, was if a physical circuit was damaged or the case was grounding out, neither of which I think represent your issue.

The blinking is common on multiple misfires, so I'm not shocked that the high Kr is flashing it also.

Re: Wondering

Did you say the case (ecu) is NOT to be grounded?

What he said?
I have mine grounded to the cab since it's just sitting in the glove box.
I figured it wasn't but wanted to hear it from others.
