Astroflex control module issues

Hey guys, I have a 2004 Toyota Tundra my old remote starter crap the bed on me right when winter ended thank goodness haha!! Anyways I justt finished programming a new astrostart remote starter all the functions work from unlocking to locking but when it try's to start it turns over and runs for about a second then the engine quits on me.     The Astroflex control module little led light with the 9 switches beside it blinks 12 times after attempting to start the engine. I looked it up in the code section of the manual it says the engine is over revving when it attempts to start??    Any feedback or solutions on this problem would be much appreciated! It's getting to be that time of the season would love to fix this problem before the snow flies. Thanks!!

Forgot to mention that the old astrostart remote starter was working just fine.

Did you learn the tach to the new unit?

If I remember correctly, switch on dip switches 1,4,5,6 while running then step on the brake for auto tach learn. Or is it 1,5,6,7? If you get it right, the park lights will flash the amount of cylinders learned.

Are there any settings to select the number of cylinders by default or manually?

Hey guys, thanks for all the replys lots of help!! I finally found the manual for the control module online and that's exactly what I did I switched the dip switches up on 1,5,6,7 with the engine warmed up and running pressed the brake to reprogram the rpms and tach i guess?? The module makes a clicking noise and the running lights blinked twice I pressed the brake again to get out of program mode and it worked. I guess the rpms were out of sync. Thanks again guys!! Cheers!!!

Sometimes that happens that the Tach doesn't program right the first time. But glad to hear its all working.

There is, but it's a combination of dip switches that I will never remember. The auto learn works great if the car is warmed up and idling.

Never used a Astroflex before so not too familiar with them.
