I have not yet received final approval from upper management to send our official post. I can tell you that we do have compatibility issues with our DIS Ignition Controls and aftermarket controllers. We have been working with the individuals from FAST and we do have a couple of Buick GN's coming into our manufacturing facility to do some additional testing.

Evidently not. Seems as there's alot more to it than switches.. as seen in the 80 some posts of prior thread

I may be way off base here, BUT
I can see where adding an aftermarket ECU such as FAST would not have any rev limit issues.
However, when using the MSD DIS4 with the stock ECU, I'm thinking no matter what is done with the MSD, the stock ECU's chip controlled rev limiter is going to take over at it's set point.
I'm at work and can't look into the file here, but if memory serves, even if one was to set the rev limiter to it's highest HEX value (FF), I think that still equates to a maximum value of 6250.
Correct?

Dave,
I believe you are right about the Stock ECM chip rev. limit being the governing factor vs the msd setting.
I think the max setting in the ECM chips can be set to 6375rpm with the ff entries. Of course if necessary the chips rev limit can be shut off.

That's what we did on Dads car. We had the rev limiter in the chip turned off. He usually shifts at 6500-6600 rpm, but it has seen 6800 a couple of times. Then
all of a sudden, it wouldn't rpm. Still not sure we have it 100% figured
out. But for now, it runs alot better with the MSD unplugged.

I can Honestly say after using all types of MSDs on all types of systems, NOTING can outperform the analog pieces!!!!

"Out tricking" ourselves??
I think Bill has come to the "right on" conclusion. It seems alot of the "trick of the month" devices look great, and in theory, could work. But they only end up causing alot of frustration, lost performance, and even worse.. Money.
It looks like the "KISS" principle wins again!!! We all know what that is.
Back to the basics...

I just installed an msd on TTA and a big stuff on a customers car and it starts breaking up around 4500.I have done dozens of these and never had a problem.The only difference is that i put this one inside the car were the stock computer was and all the TR were installed under the hood.I also noticed that the radio is scrathy.I'm going to move the msd and see if it changes.I'll post outcome.
I don't think the antenna would leak enough EMI to cause such a problem... BUT
Many plug wires WILL, especially so called low resistance "race" wires. They are extremely problematic for modern day electronic systems.

Well after putting it in the engine compartment and routing any other wires away from the msd harness,no problems.The radio sounds fine and no more miss in higher rpm.I don't know if this is the solution but it did help.Dave the wires are msd's and were on the car before and it didn't have any problems.
