HPTUNERS supports many GM 4 cylinder controllers. NA and turbo. This is one of those things where I am sure you can do it, but why would you... BTW, Hptuners also supports the 4.0L Jeeps for a few years now....

I have HPtuners. I've just had bad experiences with them and don't want to give them anymore of my money.Originally Posted by tayto
My YJ is a 1987, nothing on it, as far as wiring, is much good.
i see, good luck with your project..worst case you can run a TPI ECU ('730) it will run 4 cylinder with 4 injectors and did so from the factory. Also came in a weather sealed engine compartment mounted ECU ('727). you could also run DIS, it's not CnP but is still not a bad system and cheap. guess it's not as cool as the LS stuff, but it's bee. hacked for a long time now.
Also if you go that route unless you go DIS, you don't need a crank trigger.
You could also run custom code, such as s_aujp, or code 59
No need to re-invent the wheel. But we can make it better
I built a low resolution '0411 dual trigger distributor for SBC / BBC applications. The design is "bolt on" crank trigger parts for a L31 / L29 distributor. Maybe a similar low resolution dual trigger distributor could be used for a Jeep 4 cylinder bench test tool?

Maybe the pictures below will be helpful for 24x Jeep 4 cylinder?

only insight i have is if your running "every other" injector from the firing order, set the fueling to 1 bank. Kinda what we do on single turbo setups. It makes global changes to trims instead of bank to bank.
Sounds interesting. So this would only need 1 O2 sensor?
