Question on hooking up a tachometer gauge. Would this be the RPM Brown/White wire? Or would it be the IG3 Blue/White wire? I think in my case it would be Brown/White as IG3 is used to power the 3rd ignition coil. Correct? If Brown/White goes to tach would "pulses" be setup in such a way that tach should be set to "six cylinder" for this V6 setup? FYI, both CPU's I have work now so sending back not necessary at least for now, thanks. Tom Lang

The engine runs great on one of the two ECU's I have. However, on one of the ECU's I get no sparks, the other works perfectly. It appears that the 3 ignition "output resistors" are ok. Obviously this is probably not a user-serviceable ECU but is there anything else I could check? I think each of the ECU's are the same, however, the ID of the what I will call, "main chip" is slightly different. Can I remove this so-called main chip from one ECU and install it in the other? How do you remove it? If I want to send the one G1 to you for service, is it a flat-rate kind of affair or could it get so expensive I should not even bother considering the age of the ECU? thanks, Tom Lang

Regarding paragraph 2, it sounds like the parameters can be adjusted slightly by the tuning module, is that what you are saying? Are they only allowed to be changed while the tuning module is plugged in (i.e. adjustments are not saved in memory? Can the tuning module also display rpms, oil pressure, etc? Where can I read about the operation of the tuning module? Regarding paragraph 3, yes it is a WASP cable and simply allows remote mounting of the ECU so it does not have to be mounted in the engine compartment.

I have a supercharged 3.8L V6 engine from Wasp Marine. It came with two ECU's with the following ID's. "Link Buick V6 D42WASP3 130902" and "Link Buick V6 D42WASP3 170402". I also got a "Hand Held Tuning Module" and a long cable with a connector for the ECU on one end and an AMP 16 pin round connector on the other. 1. Is this ECU compatible with PCLink and ComLink? 2. Can this ECU be re-programmed or is it a proprietary program by the manufacturer of the engine and therefore parameters can only be viewed? 3. What is the cable with the AMP connector on the end for? 4. Where is pricing info for ComLink; I did not find it on the Price Sheet.
