Hello I am new to HPacademy as a member but not from working here and there in the past. So to get straight to it I plan on swapping a Maserati F136 engine into my Porsche 944. The Maserati engine uses Bosch Motronic ME 7.1.1 or 9.1.1 depending on which engine size (either 4.2l or 4.7l). Here is as much info I could find on the stock engine electronic system:
Stock redline: 7500
Four knock sensors
60-2 trigger wheel located on flywheel.
Has vvt on intake cams only and uses 4 teeth on the cams trigger wheel.
Either 50° or 60° of cam adjustment.
Mostly every sensor is Bosch.
I don't plan on keeping the DBW.
I attached some screenshots from a Maserati training course PDF on these specific engines hopefully that helps.
I am no newbie to engines, but to tuning them I am. I am ASE certified in both automotive maintenance and engine rebuilding. I would like to keep the price of the ECU around 1400$ or less. This engine uses the same block casting as the engines used in the Ferrari F430, 458 and California. Difference is Ferrari got vvt on intake and exhaust and a flat plane crank plus more goodies such as forged internals and a 9k redline i believe. My engines has a cast crank forged rods and cast pistons I believe. I have only seen this engine swapped into one chassis before. The Ferrari variant has been swapped twice I've seen and one uses the MS3PRO EVO I believe. I have no experience in tuning. Please any input would be greatly appreciated. Thank you.
$1400 is a pretty tight budget in my opinion, but if you're OK with spending a little bit more, reducing your knock sensors and are for sure not going to run DBW you can't really go wrong with Haltech's elite 2000. Priced well for its capabilities, doesnt have a few of the things you don't need and is pretty forgiving for first timers with regards to its UI etc. Also even though they're capable I'd shy away from a Megasquirt as my first foray into tuning, but thats just me.
I couldn't find my answer in my searches but does the Elite 2000 support 60-2 crank trigger?
Did you ever finish this project? Thanks for sharing all those documents.
