Here's an odd question: Which tables are affected by the injector size parameter? I assume the VE table uses this parameter, but do other tables use it as well? Here's why I ask: I got my FAST system retuned today by a local tuner, and it runs great -- very smooth, no pinging, etc. He did a...

I'm going to be redoing my downpipe in 3" (it's currently 2.5") and making a few other changes, and as a result I will need to relocate my F.A.S.T. WBO2 sensor. Will it shorten the sensor's life to move it within a few inches of the turbine outlet? One of my concerns is that between the...

I've been trying to find some decent info on acceptable EGT temps and probe placement, and I can't seem to get a straight answer. Maybe someone here can help. First, I should say that I don't have a Buick. What I do have is a F.A.S.T.-controlled, turbo Toyota 4x4. It's a street driven, 4 cyl...

As I mentioned in my previous posts, I need to make some adjustments to my existing FAST B2B/WBO2 configuration, and would welcome some input. The motor is a turbo 2.4l four cylinder that has recently been rebuilt. Prior to rebuilding the motor the FAST system had been professionally tuned by a...

After taking a few years off to devote time to our young son and to rebuild my motor yet again, I finally have my turbocharged Toyota truck back on the road. Or not quite on the road: it seems that lowering the compression ratio by a quarter point or so and changing cams has really altered the...

I was wondering what sort of output signal the nitrous outputs produce? I have a B2B/WBO2 FAST setup and am toying with the idea of water injection, and it would be great to integrate this with the FAST unit. The Aquamist unit I am thinking about can be controlled via a PWM output. I don't have...

Well, after almost a month of happy motoring, it looks like I'll be pulling my motor to re-ring it. :( I think I have a grasp of what went wrong and why, but I want to run it by the folks here to make sure I have the right understanding of the cause and it's effects. First of all, I should...

I think I know the FAST software pretty well, but I'm at a point where I would like to work with someone who really knows how to tune, preferrably with the FAST system. I tried one session with Terry @ The Mustang Ranch in Santa Clara, and I'm curious if anyone knows of any other tuners in the...

If possible, I'd like to verify whether my SpeedPro unit's ignition output signal rising edge or falling edge. I have what I believe is the "generic" bank-to-bank inductive box, which I use with a MSD 6A box as my ignitor. My understanding is that the MSD box triggers on rising edge input...

Had my truck on the dyno for the first time last week, and it was an interesting experience, one that has given me a few things to sort out. One unexpected question that came up was the accuracy of the SpeedPro's WBO2 sensor. The SP sensor did not agree with the WBO2 the dyno operator was...

Something that I've been wondering about for a while: I have a SpeedPro managing my four cylinder turbo Toyota. The wiring harness that Force EFI made for the SpeedPro has all four injector leads coming from the same bank (ABCD), essentially making my bank-to-bank system a batch fire system...

OK, here's a variation of the old "how do I establish base timing and proper crank reference angle" question. I have the SP installed on my turbocharged 4 cylinder Toyota, and it seems to be running pretty well -- certainly well enough for me to drive it to the dyno tuner for some fuel table...

I have a weird problem with my laptop (an older Compaq Armada 7750MT) and the SpeedPro ECU, and I'm hoping that maybe someone else can shed a little light on it. I'm running Win98. The only way I can get the computer and the ECU to talk is to boot the computer in DOS mode, and then exit DOS...

Lance, Craig, or anyone, File this as a future feature request, but it would be great if there was some way to adjust the sensitivity of the knock sensor. Maybe this isn't possible with the GM ESC module; I don't really know, but on my noisy SOHC four banger, I find that I'm getting too many...

Has anyone used a J&S SafeGuard (or their new Ultra SafeGuard) with a SpeedPro/FAST EMS? http://www.safeguard.20m.com/index.html For those unfamiliar, the J&S SafeGuard is a very advanced closed loop knock sensor/ignition management device that's capable of "almost real time" [my phrase]...
