PM to you of my phone number. But today is wedding anniversary so conversion might be choppy today. Tomorrow is open.
GM or GEP optimizer makes no difference on this. Mine is optimizer but with ds4 capable timing gears.
Wait to start and brake have no effect on tachometer. Tachometer is getting bad signal then so it trans controller. I see this as must fix first.
Nope. there is no shielding on any of the cps or ess.
It is just 2 wires, 14awg. You could make your extension cable out of shielded wire if you wanted to, rembering to only ground one end of any shielded wire. It would not hurt anything. But I highly doubt it will fix anything.
I don’t know the signal to look for - (DOES ANYONE KNOW HOW TO READ A CPS AN OSCILLOSCOPE?) nor know the circuitry. My hummer manual is a $20 chineseium knock off one someone on ebay printed out and sold for $25 way back in 2004. And unfortunately the wiring schematic section is basically blurred junk. I never have bought the actual manual because of cost (I thought it was a good deal on a used one back then and my first ebay purchase- lesson learned).
I think you really need one here because there is too many changes year to year and between pickups vs hummers.
I dont know 100% the military 2 wire CPS and mine are functioning exactly the same.
My understanding is all 2 wire sensors work identical.
@THEFERMANATOR is the one that explained the difference of 2 wire and 3 wire pickups to me. (I am sure I had it in class but it never stuck in my brain) Maybe Ferm can say how to test your 2 wire cps? Or if you should just replace it? I know it is magnetic and you could have metal shavings stuck to it causing disruption like when an a d sensor gets some on it (but that means scary stuff metal shavings in the engine). Free is removing it and wiling it clean to be sure - but I seriously doubt anything will be on it other than a little oil.
How far are you from Florida? Maybe Ferm can take on one side job? You have to do the physical work while he tells you and he watches computer screens. He isn’t turning wrenches since messed up his back. But the knowledge bowl is still full. Would be better and cheaper than ModMafia ride. There is that one amazing dude in California you can ask about on the other forum. He has the 95 computer adaptation stuff a
I am sure you are best off with someone who is an expert on the obd1 4l80e equipped trucks. You and I are in the no-mans land with the 95. I figure worse case scenario I might abandon factory trans module and go with an aftermarket stand alone if it ever comes to that.
Yours is more complicated because you had transmission issue and someone messed with it and maybe they goofed something up.
Did you add the turbo? Do you still have the ESS where you could remove turbo temporarily for test drive and install the ESS? That could eliminate the cps questions.
Do some rubber hose plumbing for intake and point up pipes downward, put flex pipe on each one pointed down to ground with bailing wire and seal temporary with the aluminum foil hvac tape. Use the “8” oring turbo oil seal and. A piece of angle iron metal using turbo mount bolt holes to plug oil feed and keep out dirt from return.
A lot of work just to verify but you really need to eliminate possibilities.
A REALLY expensive shot would be that 6 speed set up that Phoenix Hummer is doing. The trans is not as strong as a 4l80e, so rebuilding that should be estimated to be done every 100,000 miles. But MAN those gear ratios are tempting!
He has not done a db2 hummer yet so maybe a reduction in price for being Guinea pig? He said the GM engineers are working with him on this- just verify it is really a currently employed GM engineer. Then get ALL the specs FROM THAT ENGINEER of the trans and whole system so you can have it repaired/ replaced in the future if Phoenix Hummer goes out of business.
