396 Stocker Motor won't RPM

Bobby Lundholm · 10-26-2014, 05:07 PM

I have a 6AL-2 module with a dial type 2 step launch module add on. The car does not sound like a normal car when it is on the 2 step. Once it launches it will not RPM over 6,000 while it goes down the track. It has a high side 8,000 pill and no other 3 step limiter. Once it gets to 6,000 it doesn't sound like it's on a 2 step just gets to 6,000 and stays there. Any ideas on what is wrong?

Unplug ALL rev limiter wiring and try it. See it it will turn higher? Had a 3 step module do this to me several years ago. I kept checking the pills and changing pills, and it was actually in the 3 step box.
Good Luck.

Thanks. That is what I narrowed it down to after trying everything else. Too bad this past weekend was the last time the track up here will be open for the year.
Did it sound different when it was on the 2 step on the starting line? It doesn't sound like is usually does.

Sorry Bobby, but I dont remember exactly... I just remember it would not rev right and drove me nuts for a while.
Was several years ago on a bracket - 10.90 car I had. 6AL box, and when I pulled everything out of the rev limiter switch, everything was fine. I put a different 2 step module in it that I had in the trailer, and everything was good. That was after several races, of trying different things. I couldn't really tell in the garage.

Good luck,

Ken

Bobby: My brother Joe Martens (B/S '69 Camaro at the time) had a similar problem with the dial type two-step rev limiter back when he first started racing @ 2004. A Super Gas racer offered a MSD single channel digital ignition tester to use to check the ignition (7AL-2 with dial type two-step rev limiter) and it showed that the spark would break up at 6000-6100 RPM. He pulled the unit and sent it back to MSD for a rebuild. Upon receipt of the repaired dial type two-step rev limiter, the same results occurred. We 86'd the dial type and went to the pill type and it worked perfectly.

Bobby - What are you using as your add-on 2-step module? The 6AL-2 uses rotary dials for the low- and high-side rev limiters. I have heard that there have been issues with the rev-limit circuit on some boxes. Hopefully you can find some way to test yours off the car this winter!

I had similar problem at Finals this year.

Lost 1.2 in ET and 12 MPH final qualifier.

Msd checked coil ( Red big HVC/2 ) at a their booth.......Said Fine!

Jon Jr. put new coil on at PSCA and car ran perfect!

I was hoping to find out what add-on module Bobby was using on his 6AL-2. I've been looking for a way to add a third "step" limiter to my system, but from what I've been able to research the -2 has no compatible add-on module available from MSD, just the two built-in settings. I may have to upgrade to another box to take advantage of that third step.

This is the module that I am running.
