MegaJolt on Chrysler Magnum 5.2/5.9 V8

Post by abbeyroad »

Hello!

My V8's ECU is not programmable and has no knock detection (93 Jeep ZJ).

I would like to use MegaJolt to give me more spark advance to improve performance. I have built my engine with higher compression than stock and with good quench characteristics.

Here is my ideal "proposed" setup:

1. I retain the stock ECU to run the injectors and other functions.
2. I disconnect the coil and use Megajolt as my replacement coil input.
3. I tap the Chrysler Crank Position Sensor (Hall Sensor), and Cam sensor.
4. Bolt one or two knock sensors to the block (the empty dodge engine mount bolt holes seem ideal -- no?)
5. Tap other sensors - ???

I will need MegaJolt to tap the crank sensor so that the stock ECU can get a good signal out of it too. The stock ECU must continue to think it is doing its job.

What is the future of MegaJolt please? Are these features likely?

I am an embedded C/C++ software developer by career -- but have always had boards built by the-guy-in-the-other-cubicle. So I have never built boards myself. But if programming is involved it would be no problem for me to do this work.

Hi - the Megajolt will work with your v8 engine as-is, providing you use a 36-1 wheel. This is likely the easiest route for you!
