Title: ignition curve turbo car advise please Post by: mr horsepower on July 10, 2016, 12:15:58 pm I was wondering if anyone have a sort of base map for the turbo efi car
So i can put that in the ecu and then fine tune it on the dyno? Would save a lot of dyno time i think .

I'm at 24 degrees @ 35 psi of boost. E85. NOT recommended unless you have a lazy compression and use ethanol.

There is a lot of HP to be found with more ignition until it suddenly is enough and you start to knock. -BB- Title: Re: ignition curve turbo car advise please Post by: richie on July 13, 2016, 21:15:50 pm Henri
are you going to use boost compensation to pull timing? Then just use a normal N/A map and pull some timing under boost that way, something like 25-26 total at 14psi should be ok with it being watercooled as a starting point, what have you done to get compression that low? chamber shape will make a difference as well cheers Richie Title: Re: ignition curve turbo car advise please Post by: mr horsepower on July 16, 2016, 17:53:18 pm Henri are you going to use boost compensation to pull timing?

I did some head grinding and got the verry low cr pistons for it . Wil try it hope it makes some power now. Thanx Gr henri |
