Re: FMU or REGULATOR?
Do you have a wideband in the car? If so, you can tune off of that. Otherwise, you may want to have the car dyno tuned.
From your attached picture I can see that this is a drag car. Bearing that in mind, the car is primarily ran wide open. So, set the fuel pressure to a very rich setting, at least 40lbs. Then go drive it while watching your air/fuel meter (assuming that you have one). This can be done without a wideband as well. But the ONLY way it will work in that manner is at WOT. If the meter reads rich, back the fuel pressure a pound or two. Continue this until the point of either poor performance or when the meter starts leaning to the left of 'Stoich". This is not an exact science, but its better than nothing. |
