speaking stock MTX computers only no chips or mods do the tunes differ? I know no 2 engines are ever the exact same, but when you take 2 motors built to the same specs and same parts and put them in 2 dif shos of the same year, would the computers be the only variable that could make them perform differently?

As far as I know all the MTX computers should act the same. Not to say they can't but they should.

thats what we thought, so next question , is it possible for a computer to not perform as well as another computer for any reason, yet the only real sign is one car might be faster then the other?

Aside from some noted variations in the actual program logic and a handful of non-essential calibration parameters, there are no differences between the '89-'95 V6 MTX calibrations. That said, I would look at other areas of the car (such as vehicle weight, suspension configuration, flywheel weight and tire diameter) to explain the performance differences between vehicles.

Then what is the difference between a B9B & a B9B1 & a LOS & a X2J?
Almost all of the differences between the '89-'95 MTX calibrations lie within the program logic that determines how the computer communicates with and process the data from the various engine control sensors. Unfortunately, none of these logic differences are sufficient enough in themselves to effect final engine torque output, which is why the factory computer calibrations can usually be ruled out as a factor in vehicle performance variations of the same year or generation.

Can I replace my B9B1 in my 89 with a LOS?
Yep. All 49-state V6 MTX computers are freely interchangeable without problem or incident.

Thanx Adam! So is there any Benefit at all in swaping them? I thought that the B9B's had to swap to LOS at least to use the stand alone chip (LPM) I have an old SS LPM from a MTX that I wanted to have re-flashed for my ATX for your improved shift program but...... So can I put this LPM on my 89 with the B9B or do I have to swap in a LOS? That way I can at least use the damn thing since I did buy it!

In my opnion the X2J is the best MTX computer. It seems to have the best drivability ofer the others.

I was also under the impression that if you have an LPM/chip, that it must stay with the computer it is programmed with. In other words, no swapping your Hypertech chip from a 91 (LOS computer) to a B9B1. Isn't this correct?

When it comes to the TwEECer, you can plug that sucker into any EEC4 computer.

Other than the usual driveability improvements that Brian noted with the '92-'95 X2J "upgrade" or the need to run an old ribbon-style LPM, there's no need to trade a B9Bx computer for an L0S or vice-versa.

So can I put this LPM on my 89 with the B9B or do I have to swap in a LOS? That way I can at least use the damn thing since I did buy it!

Technically speaking, you can use any old ribbon-style LPM on any V6 SHO computer with the right programming. It all depends on the the person that reprograms your chip and the method they use to store the new calibration data on the memory module.
