The child in me wants to fire it up because red valve covers!

Putting a proteus on that engine, albeit not in the Coupe anymore.

Please share your F136 tune once you have it. How is it looking?

I see not today

Note to self:

This body uses this version of the 121 pin header

I have 2 donor quattroportes (M139) with the ME7 ecu, going to grab a Hellen 121 for testing, curious to see what I'll be able to come up with and curiously following this build. Standing by for those tunes too

Please carefully review the pinout in advance, it should be fine but who knows

Went and did some cross referencing and it looks like everything lines up according to my wiring diagrams and the Hellen 121 pinout sheet. All 8 injector and coil outputs are where they need to be as well as the etb, tpp, and maf. Main relay and power inputs are a match as well. everything lines up perfectly. It is sad there is only support for 1 knock sensor right now as these engines have 4 but I'll live. I went ahead and made a copy of the 121 VAG ECU pinout spreadsheet and added my findings to a later column for my personal reference if anyone wants it. There are some differences such as the addition of high and low speed fuel pump relay outputs and some others but otherwise almost mostly the same.

Column Q

I'm getting closer to running...

Oh thats gorgeous. Did you do any internal work? I've seen one car in our shop with the Novitech supercharger kit but it also had upgraded internals for the boost. Since these engine run 11:1 compression ratio, I'm curious what boost levels you plan on running.

[mtmotorsport]

Relatively low. I've had the engine apart and the internals look easily up to the task of 750hp. E85 will be used for attempting to reach the target of 750hp. Twin GT3076R's are used to motivate it haha.

Very neat, can't wait to see it running.

Working on getting the pinout sorted for the F136 4.3 found in the Ferrari F430, I'll update the sheet when I finish. There's 2 additional variators for the exhaust cams and 2 additional cam sensors so the ecu is basically packed to its maximum pin usage with some extra equipment. Firing order is different with the engine being a flatplane configuration vs the 4.2 and the 4.7 crossplane found in the maseratis.

I'll have to hold out on getting the 121 VAG as I had to take my furbabies to the vet for an emergency and they take priority over hobby stuff. I'm also working on a hardware PID list and CAN message database to control the F1 gearbox independently and do some other fun stuff involving the other modules in the car. I'll make a separate sheet as I work through it.

The F458 is similar to the F430 in the crossplane department using a 4.5l variant of the F136 but a different ECU and direct injection.
