First run on a fz750 with small result.
Used gsx 750 throttle bodies, r1 injectors. gpz 1100 fuel pump. Build a mini-ms with ms-2 onboard .

First time fast start, only my map signal stays around 100, so to rich running. Wondering how to convert the ve table to tps.

Still going :)

Hello Pommie,...didn't received the msq, would be nice to see your efford and i think it would help me a lot.
In the meanwhile i just redraw the fuel table starting at 0 to 100%. Must say that it works well..as far it is driving with some hole's in the powerband. But that is just tuning :)
You where rigth about the use off tps. The map sensor won't work, to spikey and to high.

The only real problem is the cold start. Must cranck a lot before any starting. I think it is to lean at the bottom. Still trying and going steady..

But at the rigth revs...it drives like silk..so smooth :yeah!:

Just out of curiosity, why did you change from the gsxr injectors to r1's?

Hi cahillicus

Had them in stock. Wanted to use the R1 bodies but it didn't fit in the frame. Made the wiring ready for this so when i changed to the gsx bodies it was easier to use the r1 injectors, although the injectors are the same size and fiting.

Changed to SD to see if the response is trhottle response is better. VE table is beginning to become a ice one...but acceleration is horrible.
