PounceBounce posted a topic in G4+I've got an FD rx7 with a PNP g4+ ecu and I'm struggling to find which ignition channel correlates to which spark plug. I have the following information of the stock configuration but need to know which between IGN 1 and IGN 4 which one is Leading Front and Leading Rear. I would assume Ignition 4 automatically becomes Leading rear? But dont want to risk any engine damage. IGN 1 = Leading Plugs (Pin 4AN IGN 2 = Trailing Rear (Pin 4AJ) IGN 3 = Trailing Front (Pin 4AF) IGN 4 = AC Clutch (is now wired to coilpack 4 for direct fire) (Pin 4i) IGN 5 = Expansion Loom set to AC Clutch. Hopefully someone can help or can give me an idea on how to figure it out myself!
PounceBounce posted a topic in G4+I'm really hoping this is the correct place to ask this question, and I apologise if it isn't! I have an Rx7 S7-8 pnp G4+ Ecu that I'm using on my Bridgeport 13b. I'm ditching the stock ignition set-up in favour of the LS1 coil packs that are known to handle ignition demands much better in higher power situations. I'm hoping to figure out a way to run the leading plugs in direct fire, the same way the trailing plugs are. As the coil packs will struggle at higher RPM in the original wasted spark set up. I've found the factory three ignition outputs from the ECU for Leading 1 and 2, Trailing 1, and Trailing 2 and I've de-pinned them from the Ignitor plug ready to wire into the LS1 Coils. I'm now at a loss as to what to use for Ignition 4 as according to the manual that has been appointed to the Aircon-clutch (Which I intend to keep in the car). Is there another output I can set that to? Or will I need to purchase an expansion loom to gain Igntion 5,6,7 and 8. (I'd rather not purchase an expansion connector if avoidable, just to be able to run one more Ignition output for direct fire). I've used the help system to determine how to change the ignition mode to "Rotary - Leading Direct". I'm sure there is a very simple answer I'm missing and I apologise for that in advance! Thanks!
balldlox posted a topic in G4Hello, I have transplanted a 13B into my 72 super beetle. The FFE trigger only has 3 wires and the general G4 instructions call for 4 wires. What is the correct way to connect them? Any help is greatly appreciated. G4RX, AEM smart coils, FFE hall effect.......
I've a 13b turbo in a new Tatum offroad desert car. It's proving to be a powerful powerplant and up to the task of offroad racing. However I do have an issue that may see me thrown out of most endurance events (especially that of forests). That issue being the short exhaust, and the fact that I'm working the car hard, proves to produce quite a bit of flame on gear change (a sequential, so changes are quick) and any decel. I've tried trimming the vacuum part of the map, however it appears to be firing the instant I rock into decel. I've also thought about using decel fuel cut (and haven't tried it yet). If I do so, should I remove the ignition retard? The theory being that it's a race car that requires instant throttle response and as such don't have the opportunity to wait for ignition advance to be reintroduced. Cheers, Daniel.
