I have been trying to get my conversion done in time for Okteenerfest. I have run up against a brick wall and just cant seem to figure out what i am doing wrong.
If anyone can help me by looking at my tune files or providing insight it will be very much appreciated. I can get th car to idle but nothing beyond that. Any use of the throttle is less than impressive and almost useless. Meaning it bogs down and does not accelerate at all. I have no clue what i am missing. 2056 with new low impeadance injectors. Bosch Wideband O2 sensor. Really need some suggestions. Not sure if i can post the tune files here. But will try. |

QUOTE Seems to be too simple? Ignition is simple.The coil you pictured (and most like it) have two ignitors built in, which controlled by the blue wires in the above picture. The ECU triggers each wire separately, every 180degrees. The spark plug outlet/wire connections are paired. So the coil pictured above the top two connections fire simultaneously (pair A), and the bottom two fire simultaneously (pair B). This means that each cylinder fires twice per cycle, this is not like the stock setup. The ECU is hardcoded to trigger IGNOUT 1 as cylinder #1. So cylinders #1 and #3 get connected to the coil controlled by IGNOUT 1, and cylinders #2 and #4 connect to the coil controlled by IGNOUT 2. The firing order is set by your spark plug connections. This is Wasted Spark. If it's still confusing, research Wasted Spark because I bet that will clarify things. But there's not software setting for firing order. You just have to hook it up right, which really is just like a standard distributor. You can screw up your firing order on a stock engine just by swapping two wires. Same thing with the coil you pictured. You can screw it up (or make it right) just by moving the spark plug wires. NOTE: Some coils come with cylinder numbers embossed/scribed into the body of the coil, THIS MAY NOT BE CORRECT FOR YOUR ENGINE. Those numbers are to guide/help people installing that coil into the car it was designed for. You're not doing that, so those numbers (if they exist) aren't for you. Sand them off or just ignore them. tl;dr -- Firing order is set simply by hooking the spark plug wires to the correct spots, and that's all. |
