performance chips

[Zieg]

I have an 87 Euro 6 cylinder 730i M30B30 powered 7 series. I have gone to several companies like Turner Motorsports and Pelican Parts to ask about a performance chip for my car. They both responded that they have chips only for 735's. I would guess M30B34 motors and newer. They say the chip for that motor will not fit mine.

Does anyone know of a chip that I can purchase that will fit my car?

What is the Motronic end number from Bosch on the Motronic? I have chips for the M1.1 and also for the M1.3 Motronic. Sold a lot in Europe for the M30. Probably can help.

Hi Shogun;

The numbers on my Motronic system are O 261 200 151 second set of numbers are 1 708 581 does this help?

The Bosch number is important, O 261 200 151 , that is the M1.1, have a chip on stock.

Eventually I will probably buy one from Shogun, either that or I will go the miller MAF route.
