    Not firing on all cylinders. Motec M48

    So looks like I'm caving and going back to the original single throttle body setup for now. Tried running again today with a fair few adjustments on tune. The dizzy was out and we put it back in at TDC. This time cylinders were: 1 warm/hot 2 hot 3 hot 4 warm/hot 5 hot 6 cold 7cold 8 cold...

    Not firing on all cylinders. Motec M48

    yeah it seems the next step is to check the timing out and to see if there are any air leaks. Will keep you updated with the next symptoms/successes!

    Not firing on all cylinders. Motec M48

    Yeah the other system was using the MAP which went straight to the ECU. Currently Ive got it running to the MAP sensor. From what I understand there is a plenum in the middle of them to allow vacuum but I'm not sure how efficient it is. I'm guessing it would be quite different compared to the...

    I didn't know this was a thing. I'm not sure. Its allowing me access to it so id assume not. how does it calculate it and how much do you normally get?

    Not firing on all cylinders. Motec M48

    Thanks, I will get into it this week and see what I can come up with. Sounds like it could be a promising path to take. But if this was the issue how come it was the same with the msd8579 and msd 6AL box? That's a different setup and was having the same symptoms.

    Not firing on all cylinders. Motec M48

    I will look into seeing if I can get the flow meter to test the itb's. It was a self learning ECU and was batch injection. I thought that may have been causing the Initial problem and now I went back to the motec m48 that was running just a single throttle body. So in that respect nothing has...

    Not firing on all cylinders. Motec M48

    It is possible that the engine wasn’t exactly on tdc. There isn’t a good mark on the engine but I’ve found something I believe to be the correct markings. The dizzy was put in around 5 BTDC. The tower position is definitely correct though and the motel knows the correct firing order, It could...

    The msd box isn’t in it anymore as I had to go back to the old distributor to run sequential injection.

    Not firing on all cylinders. Motec M48

    Haha that’s half my life ago, it doesn’t run a crank sensor. It’s all controlled by the dizzy i believe.

    Not firing on all cylinders. Motec M48

    Hey gents, the firing order is set to the 351 firing order being the 5.0. That’s all set correctly and checked multiple times. The base signal is coming from the distributor, it’s got 4 wires coming from it. I was going to use the msd8579 but it can’t do sequential with a crank signal. The...

Im trying to connect my M48 to PC for the first time (has been connected before with previous owner), however Ive run into a wall here. The software version I'm currently running is V6.2...

    Fuel Map

    Hey Guys, Ive tried searching and couldn't see anything that will help but maybe i'm searching the wrong words or something. Does anyone have a base fuel map for a 302 windsor or have any knowledge about tuning that can help me out. Im using the base map that came with my system...

    Hey Guys, Just wondering if anyone has any tips or troubleshooting guides for the speedmaster turnkey efi. I have the car fired up but it is running super rich and using the heat gun it seems that cylinders 1.3.5.6 are not firing. It also seems there is fuel getting into the cylinder and the...

    Dizzy wiring

    Hey mate, all I know is it’s a scorcher distributor with 4 wires coming from it. The wiring diagram for the old motel system says it’s : A. Earth (black) B. Ref (green) C. Sync (blue) D. Power (red) I would like to just use the same distributor for the new system I’m running...

    Dizzy wiring

    Hey guys, just seeing if anyone knows if I need to use all four wires on my dizzy. The new ecu loom only has 2 x wires going to it a green and a purple. The old dizzy (scorcher) has 4 wires. An earth,power, sun and ref. Is it a matter of just using the power and negative or does it need the...
