Greddy E-manage

well, the mk2 ignition system is nothing like 7mgte multi coil system and we should not have such problems.

if it works, I want to try and use the e-manage as a single solution for a turbo bolt on. we'll see how it goes. for now I will just write about the installation and possible getting the ignition adjustment to work.

they are kind of similar.
the igt signal from the ecu to the ignitor on both the mk3t and mk2 systems is pretty much the same. the 7mgte handles multi coils in the ignitor. the ecu sends two logic signals to the ignitor to let it decide which coil to fire, so it's kind of like the mk3t ignitor is an electronic "distributor". the mk3t ecu might be a whole lot smarter, but both computers receive a spark confirmation signal back from the ignitor, and both will have the capability at least to see that spark did not happen at the time it specified. or maybe the confirmation signal has nothing to do with it, maybe the mk3t ecu advances based on knock sensor feedback so it corrects when pulling timing. *shrug*

the thing is, the way they made it sound on the supraforums thread was that the mere fact that they had the e-manage set up for a distributor made it unable to retard and only advance timing. i dunno what's up with that, man, maybe you could ask one of them.

in any case, all conventional wisdom would say that the e-manage will be able to pull timing. the only things to worry about with our cars are that the computer gets a spark confirm. signal and that the ignitor controls dwell. but that doesn't seem to be too specific to toyota.

anyways it'd be really neat if you got it to work well with a turbo set up. good luck with it
