Default M44 Supercharged Project Tuning - Bosch Motronic 5.2

Hello Everyone, If I am posting this in the wrong section of subforum, then my apologies. I am known in the other forums for the Supercharger Kits we do for the 6 Cylinder variant of these cars. We are the hardware guys ofcourse and tuning is not what we specialize in. We will be working on a very budget friendly DIY SC Kit that will be available to the public like our other projects.

Issue is the M44 has the Motronic 5.2, Its Its flashable IIRC but how do we go abouts it, for the MS41 type ECU's in the OBD II 6 Pots we have Rom Raider. But for the Motronic 5.2 there are only a few people who know how to do that ECU right. Suggestions welcome. We would eventually need a remap, dialed in injectors etc etc. looking at around 5-8psi of boost.

Look up techniquetuning.com, and give Nick a call. He did a software upgrade for the M44 with the Downing Atlanta supercharger, which is no longer produced.

Alright, Will do. We plan to use the AMR 500 and the Eaton M45. Any other suggestions do let me know!

Has anybody looked into the Ostrich II Piggyback on these cars?

This would be very exciting and you could almost count on a purchase for a complete kit from me, depending on price/contents obviously.

Heya! Well I already did some rudimentary tests and superchargers that will fit while maintaining the stock manifold so far are the big SC14 1.4L Roots SC, and the little 500cc AMR 500. Next steps I will be making a build thread and moving the battery to the trunk. Once thats done we can test and see if the M45 and M62 will fit. Then we have a real nice easy to produce kit that we can offer as a bolt on that will allow you guys to go to any yard and bolt on a blower for next to nothing (plus buying the kit that is which will be priced likely 1/3 or less than of any known competition).
