Notice– there was firstly an blunders within the ms2 tfi doctors that stated to depart r43 out for this setup, i’ve determined that to be incorrect and it’s been corrected it within the ms2 docs, so go away r43 in!.
To wire this up without the relay board (directly to the ecu), wire up the recent twine from the idle valve to switched 12v (warm in run), and cord the poor wire from the idle valve immediately to pin 30 on the megasquirt db37.
Based on a far flung mount tfi module and a separate distributor.? equal tale because the 87-93 for the most component, you just get the return the signals to specific locations.? basically you get the tach enter to the megasquirt (pin 24) from the pip sign at the tfi module, and you send the outgoing ms ignition signal returned out from pin 36 to the spout pin on the tfi module.
Automated transmission: the ’86-’93 fashions do not have the ecu controlling the transmission, so you can take away the factory eu absolutely and now not have it affect the shifting. ??94-’95 models have the eu controlling the automatic transmission. If you have such a vehicles, you could both do a parallel installation and leave the inventory ecu in fee of the transmission while the megasquirt controls the entirety else, or add a gpio board jogging megashift.? if you’re doing a parallel installation to preserve the stock eu on top of things of the transmission, see this text for tips on parallel installs.
Note– there was initially an errors inside the ms2 tfi docs that stated to depart r43 out for this setup, i’ve determined that to be incorrect and it’s been corrected it inside the ms2 docs, so depart r43 in!. If you have an ms2, you may use the two stepper iac outputs to pressure the relays – just twine the 2 iac1 wires throughout the coil of the low velocity fan relay, and the iac2 wires across the coil of the excessive velocity fan relay. The ecu did not manage the fans on ’93 and in advance models.
