Default Re: Injecting water into a rich a/f mixture is not a good idea

I have a slight problem with my pending install - and after reading this it seems I may struggle to get success without a retune ....

Basically the car runs very rich (sub 11:1) - typically because its oversafe position and also for IAT cooling... motor has a hoplessly small I/C which cannot cope and ECU pulls timing once IAT's reach 60C, and starts to pile in fuel from there on up ... at 90C the blower shuts down...

I am curious how the ECU map is configured for lower IAT's in terms of AFR's/fuel flow ... so guess I will only know this once the system is up and running...
