Hey Adam, just thought I’d update you. I rewired them and it’s all sorted. Thanks!

Sorry I worded that wrong. When I do the test ign1 coils 1 and 4 fire. When I test ign2 though 2 and 3 don’t. I’ve confirmed that the coils aren’t dead by switching them around etc etc

Ok will do, any ideas why only one is firing though?

Hey all me again, I’m trying to get my Yaris COP conversion for my MX5 NA working. I’ve wired them in as per the photo attached below but when I do the coil test only coil one is firing, which is in cylinder four when it should be in cylinder one? I’ve switched the coils around to make sure they aren’t dead and used the correct Yaris COP dwell time. Any ideas? Thanks!

Ok thanks, I’ll splice pin 21 to pin and and move the signal wire to pin 7 and report back. Thanks for the info

The stock harness does have 5v, signal and ground at the tps as seen in the photo attached. So there shouldn’t be any additional wiring needed for a 3 wire vTPS. I guess all I’m asking now is basically, I need to move the pin from the stock ecu location to any AN volt, either pin 6 or 7 right?

Ok, I think I’ve wrapped my head around this if someone can confirm. On the stock wiring harness pinout the TPS comes in on pin 21 which is NC on the LinkG4x. Would it simply be a matter of depinning it and wiring it into AN Volt 1 on pin 7?

Hey all! Im struggling to understand how to wire in my vTPS. I have the link G4x designed for my 1990 Mazda MX5. The manual says that the MX5 doesn’t have a factory fitted TPS but it does, just not a vTPS. On other ecus it’s simply a matter of plugging in / wiring in a vTPS into the factory loom and selecting the right input in the ecu. I’ve plugged the vTPS into the stock wiring loom but the ecu is not receiving any signal. I didn’t think any additional wiring would be needed. Kind Regards
