Sooo...after sitting on a full N20 bottle for two months, waiting for an answer about an MSD window switch on my '95 LT1 w/Delteq ignition, I'm now going to f**k it all and run it.

Please tell me if I'm going to destroy my engine:
100hp wet shot
NGK TR6 plugs
walbro 255lph pump
30# SVO injectors

Rest of the engine just BPU (delteq, K&N, JET performance module, TB foil). Full throttle application after 3k rpms.

106mm

I've been blasting 150 shot to my stock 94 for a long time. Don't over rev it and don't engage it under 3 grand (I actually engage mine at 3,200 rpm). Confirm adequate fuel supply and pressure and you'll be fine!

years back I ran without a window switch and never had a problem but
like 106mm said don't over rev it and spray above 3000 rpm


I notice you have a jet module...it may provide too much timing

106mm

Good call! I'd look into it before spraying it.

Somebody told me that Jet messes with the timing...does it advance or retard timing??? I'll look into it...

106mm

If anything, it would advance it.

So long as you are triggering off the ignition control wire (white), it will function normally.
Wire it in near the ecm. I think it's like pin a12 or something, Id have to dig my service manulas for that year to be sure.
The delteq merely uses the low res signal to decode which coil to fire, then waits for the ignition control wire to tell it when (angle).
At the very worst you will need a pull up resistor to get a clean 5v squarewave. But thats only if the additon of your window switch causes a voltage drop.

Mr. Bald,

Would you be able to tell me with certainty which line off of the ECR to tap??? That would be immensely helpful...

BrianCunningham

thanks for the heads up about not being able to get a window switch that works with it.

lcvette

can you use MSD with the delteq setup? just curious?

Pin A13 is the tach wire. It will supply your window switch with the correct 12v squarewave you need to trigger your window switch.

Baldturbofreak

Yes you can but you'll need a multi channel Dis-4 or 4 msd boxes.

You are badass, my friend.

Now...if I only knew which pin was A13...is it the only white wire on a '95?

Hey Clay, what up dude. Hey, we should get together this weekend sometime. I would like to see your set up and check out your ride.
