First off OBD2 computers will only work with DIS type ignition systems; and the engine must also have the additional crank sensor that is behind the crank balancer as well as the cam sensor. If your engine does not have these items, you cannot use an OBD2 computer. To answer your question, yes, the OBD2 computer will control a 4T60E transmission. I have programming available for a 3100 V6 4T60-E application that already has VATS disabled from the factory (1998 Grand Prix).
Newer OBD2 computers are compatible with the 4T40-E/4T45-E and 4T65-E transmissions; but these newer computers have VATS security that cannot be easily bypassed. These newer V6 computers that use PassKey 3, PassKey 3+, and PassLock VATS systems CANNOT be reprogrammed to disable these security systems with the tuning software that is currently available; I've tried.
Now there is another OBD1 computer option available if you want to use a 4T60-E transmission. The 1993 Lumina (and other W-body cars) was available with a 3.1L DIS V6 engine and a 4T60-E transmission. The computer used in these cars used the $DF code mask (same as 91-93 3.4 DOHC) and did NOT use the additional crank sensor nor a cam sensor. This is an underhood type computer (like the 1227727) but still had a removable chip. You MUST have DIS on your engine if you want to use this computer.

Yes a Fusion Solder Splice has the solder and the "glue" at each end:

There are other companies (like 3M) that have similar splices.

Which A/C compressor do you have?

No wonder the wiring connectors don't match... LOL. Unfortunately, I'm not familiar with that engine. So I can't help you with that. You could try the 60degreeV6 forum.

Good luck with that. I haven't been able to find resonably priced "automotive grade" wiring except at the junkyard. I would stay away from the stuff autozone and the other parts stores sell because the last time I used this stuff the insulation on it had a relatively low melting point. The automotive grade wiring's insulation does not melt when you are soldering wires together, so it's pretty good stuff. |

Here you go by the foot, haven't ordered any yet because I'm not sure what gauge to get for best current flow to and from sensors without over doing it;

Hey Darth,
I recently did the 7730 ecm swap with my 3100/4t60E (manually shifted) swap. I spliced in the correct connector and changed the vss road speed constant in the chip(24000ppm) so the ecm reads the correct speed. My problem is that the speedometer is way off. At about 20mph the speedo is pegged. Do you have any idea to fix this problem so my speedo works accuately?
Do I need this "Speedometer signal convertor" from FieroAddiction? http://www.fieroaddiction.c...ath=2&products_id=12
Thanks,
Joseph
