HFS4 on 996tt

[zx9rmania]

now is ok, was a wrong wire....like 1.x-2V at idle.. As i thought i am injecting too much meth I put just one 0.5 injector and car still boggs when kicking in... it can not be too much meth i supose.... we were running a very low mix like 30meth/70water. AFRs are going like 10.7, i am targeting and reaching 11.8 AFR on pump only. With 2x1.2mm we measured up to 7-800cc/min flow, injectors are 80cc and IDC at 1.5bar is like 70% peaking 75% sometimes

My install was also validated by another user fo yours cipsony who owns a very nice and fast audi ttrs, thank you Ciprian !


A 0.5 injector for this engine could do so much harm ? Besides retuning ??, i dont know what to do, i am lost......
