This is incorrect!! Fuel cut is the ECU slowing the fuel injectors to idle, To stop the car from breaking itself. It stops it when the AFM is reading higher than a predetermined frequency. That is why its a general range, because of air temp, humidity, barometric pressure, etc. It is not the fuel pump failing. If you hit fuel cut it feels like you just broke something, and the CEL will come on for a little while. And detonation happens because the inside of the motor is getting so hot when the piston is on the way up it detonates the fuel before the sparkplug does, also not because of fuel. It can detonate because of lean air/fuel, but thats not all that causes it. And not matter how much gas you have, the ecu will still cut it just the same. Its about air! not fuel. But of course they must match. All the lex afm does is let unmetered air go through, and the 550s to make up for it. which is basically a crap shoot with tuning.

You guys sound like you know enough, but there is no need ot fight. I don't have much to spend on this car right now, therefore, when I do something, I like to do it right the first time and not half step. If I use the HKS VPC as an afc, will that be sufficient? Like I said, I don't want to buy something now and in a about a year, by the thing I should have bought when I do my rebuild.

First of all AFM's run on voltage not frequency, its not a motherboard cpu. Ever read live data from a scan tool?
Guess what happens when there is not enough fuel? Detonation. Air is plentyful, you will never run out of air on a motor. It's fuel you will run out of. Which causes the Air Fuel ratio to spike, causing detonation. All of this happens faster than you can blink your eye. "And detonation happens because the inside of the motor is getting so hot when the piston is on the way up it detonates the fuel before the sparkplug does" Nope, thats preignition. Detonation is an explosion inside the cylinder no matter what stroke the piston is on and it usually results in a hole in your cylinder block. I've seen it before. "also not because of fuel"- No, its because of lack of fuel that the stock fuel pump can not deliver. "It is not the fuel pump failing." Never said that, please quote me where I stated that. |
