    Looking for ACCEL CALMAP DFI software to install on laptop

    It's not likely to work on any computer without an on-board serial port. It will be hard to find a laptop that can run this software and connect to the ECM.

    Classic Fast B2B ?

    Hey everyone, that's my email address up there! Feel free to use it if you have a classic box that needs some help. What was the part number of your broken box, and what part number is the new one?

    Looking for a tuner in the Chicago area with a load dyno

    Hi Aaron, yes I do. The chassis dyno I use up here is a Mustang eddy current in-ground dyno. It can do steady state like you want, conventional WOT stuff, road simulation, etc. I've dialed in a few cars on it for driveability stuff and it's pretty nice when it hits the "real" road. It's a...

    Engine almost stalls when fan turns on

    One of the options on the old Gen 7 systems is one that I still like (and is still used in OEM applications I believe) and that is an option to kick the IAC open a few ticks when the fan output is activated. It's called feed-forward (predictive, as opposed to feedback which is reactive) and it...

    Looking for a tuner in the Chicago area with a load dyno

    Hi Aaron, I'm a few hours away from Chicago but I could certainly work with you if you are still looking for a tuner. Let me know if you are interested and we can talk. Thanks!

    FAST Classic sequential vs Bank to Bank

    Hi everyone, I just responded to Abe in a PM about this but I believe the SEFI Buick boxes did have ESC control available, just as the B2B systems did. As Cal mentioned there were some options at some point (for the SEFI) that allowed that input to be used for other functions such as...

    Accel Injector Info Needed

    That is a cool feature. Fluctuating battery voltage is such an issue when it comes to dialing in the idle of a car with lots of injector and this really helps to offset those negative effects when properly calibrated. Correct me if I am wrong... didn't the Gen 7 actually have this feature...

    Classic Fast with 2 bad injector drivers

    Connecting to different outputs is not an option with a sequential unit. With a B2B you could do it but not in this configuration. I can fix it if it's broke. I'll respond to your PM with more info.

    Accel Injector Info Needed

    Depending on where you set the offset as compared to the original value of 0.8 it may not run at all. If you kicked it up to 1.9 my guess is it will not run for more than a few seconds if you start it up with that setting.

    Accel Injector Info Needed

    That change doesn't take effect in the Gen 7 until you turn the car off and back on. Hang on the next time you start it, it's probably gonna get real stinky real fast.

    Accel Injector Info Needed

    The offset is a global value intended to encompass all these things. As I mentioned before, it is intended to represent the time elapsed from the instant the driver signal goes low to the time that fuel actually starts spraying out of the injector. Coil rise times, pintle movement, and fuel...

    Accel Injector Info Needed

    I really don't think that .2 to .4 mS is a valid offset time to use. The time it takes for those things to actually start spraying fuel from the instant the signal is applied is going to be closer to 1.0 to 1.2 milliseconds for a low-impedance injector. If you are looking for a way to get...

    XFI and ditching OPTISPARK

    I know you are very much against using the Optispark for anything, but if it is used only as a cam signal in a COP setup, it will probably fare better than it will as an actual ignition distributor. One of the more significant pitfalls of the Optispark that I have been told of is that the...

    MSD vs XFI vs Classic Fast

    Hell yes there was! Those boxes were wildly inconsistent in the minimum dwell time that the box would recognize on the points input. Long before the HO, all their stuff had a 750 microsecond minimum dwell time by design and they were reasonably consistent. Some braniac at MSD decided to...

    Wifi for fast and MSD box?

    I've done it before. With the antennas I was using at the PC and in the car I only had a range of about 800 feet, and the data logging rate was reduced. Long story short it is possible but you would certainly be in major violation of any sanctioning body's rules against live telemetry systems...

    GEN7 Basics

    There are many factors involved that could make a difference, but ideally you would have the throttle blade set so that you idle at the targeted RPM with a low IAC count. I'm not familiar with increasing the airflow through the IAC at idle becoming a popular tuning strategy, but I wonder if it...

    Classic FAST changes

    I've lost track of the original problem here. However, the serial number being 0 shouldn't impact things. I programmed a serial number in it before I shipped it to Joe but as I recall there was a problem some time afterwards that caused the ECU to lose its serial number. I had to make a...

    Massive O2 reduction during decel

    Don't sweat the -25% correction on decel. It's pretty common. As long as you can tip back into the throttle without a hesitation when doing so it won't have any negative impact. If you tip back into it, it should immediately zero the correction as it begins applying enrichment fuel.

    XFI tip? Stalls when shifting from Park to D or R

    This can be a tricky area to tune on some cars. Most important thing IMO is to make sure the IAC motor is only slightly open at a hot idle in park, like 15 counts or so at the most. Try taking some timing out of it around the idle region too.

    Injector Driver Going Bad?

    There's no average life that I would say. For the most part they last forever with failures being rather rare for at least 80% of the classic FAST systems in service. Systems shipped in mid 2004 or later may have been built with a supply of injector drivers that are more prone to failure than...
