So if I don't feel comfortable taking it all apart how careful do I have to be with the cleaning process?
I have some PCMs that have a fair amount of oxidation and would like to clean them up and stop the oxidation with paint/primer. Is generating static charges from using power tools a problem - I...
This may be applicable to a lot of ECM/PCM's but I'm only interested in the P01 (0411) PCM. I have virtually no circuitry knowledge so if I'm crazy just say so. How difficult would it be to add...
I knew I could pick type but don't recall being able to specify 1 or 2 - I'll have to look again. I started to use the 2-wire flat response KS but wasn't sure how to wire/pin it on a single-wire...
I'm using a single KS on my 454 BBC because I can't find anyplace on driver's side for the second one - don't know if you have this issue or not. Since these are the single wire type and the 0411...
Hmm, well after posting the "similar threads" suggestions addresses batch fire a little but those threads are 3-5 years old. Anything new in that period of time and specific to the 0411?...
Can the 0411 PCM be configured for batch fire? How does one run in Speed Density mode? Do you merely turn off the MAF in the OS? If one runs in SD and the PCM defaults to "limp home" mode that...
The distance to the sensor (as discussed in the linked thread) I'm sure is important but since I'm using all oem parts I'd like to think it won't be an issue. But I'm not sure I understand why this...
Does the crank reluctor need to be centered on the sensor - would anyone have a picture of a Gen VI setup? I'm doing a custom build using the Gen VI timing cover and the reluctor is slightly off...
Apparent solution - works for me - just made the change.

Has anyone driven an Autometer Tach with the 0411 ECU (pin R10)? I am also using it for the Aeromotive Fuel Controller - but Aeromotive says the output signal is 5v and it needs a pull-up resistor...
I may have solved the problem - I had wired in an override switch so I could turn the fans on at any time and it appears I had a short in the switch - after fixing this the fans do not come on when...
Well today the scanner won't link up - have no idea why. If its in LHM will it set a code indicating that?
Sorry if I wasn't clear - engine is not/has not been running - I said when "ign is on" the fans come on (hi) and it doesn't seem like they should - particularly when everything is at room temp. I'm...
Well, the PCM has not been tuned/programmed yet - it is just a take-out - maybe I just got lucky. I will check out the ECT and a/c press tomorrow.
No I didn't ground the relays individually, I...
Could not find OS but I found VIN and it translates to a 2002 GMC Sierra 2500HD 2WD.
I take that back - there is a CAL ID - 12212156
Its an Actron - guess I can try and see - will probably be tomorrow though
No, not yet - I have a scanning tool - will that tell me?
Have no idea - can I tell from the label on the ECU?
I just finished wiring my 66 Nova with new harness and Speartech EFI harness. When I power up (ign on position) the vehicle, the 2 fans come on high. I have 2 fans wired with 3 relays for lo and hi...
Thanks for clarifications. -Bob
Any downside/issues to using a 0411 ECM and harness on a TPI (since I already have all the pieces)? -Bob
Thanks - appreciate the suggestions
Could you elaborate on that a little?
