Hi guys,
To cut to the chase ive had this car for over 15 yrs now 94 R33 GTST. It is modified to support 500hp on e85. A few months ago now we were cleaning up the maps in the vipec ecu when the car started to act as if it had no/low fuel. So switching it back to 98 ron it picked up again and was sucessfully mapped on the dyno. However when taken on a road test it started to do the same thing. So like anyone would we replace fuel filter and fuel pump and to our surprise nothing changed. My friend is a proficient tunner and for months now the solution to our problem has eluded both of us. At witts end and cant figure out what is happening to my car. Any ideas ?? Injectors are all flowing fine.
