jakesae101 Posted November 30, 2012 Share Posted November 30, 2012 after someone to giz a hand / and or do the job for some cash / beers whatever I think I have most of it sussed but would been keen for someone who actually has some more clue about what they are doing than I its a lem v4 and its a 1988 ae92 gtz trueno Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted November 30, 2012 Share Posted November 30, 2012 I know how and what to do, and have done before but I don't really want to actually do some work. I also have a LEM to wire onto a 4AGE that I should really do for myself. I would happily drink your beer and tell you what to do... How far have you got?

AllTorque Posted November 30, 2012 Share Posted November 30, 2012 That would be like a live tutorial! What better way to learn? Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted November 30, 2012 Author Share Posted November 30, 2012 Have got as far as working out most of what i need to wire up have questions about switching supercharger , water injection and what to do with the factory vsv setup Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted November 30, 2012 Author Share Posted November 30, 2012 Also have the mitsi ignitor to replace the factory one Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted November 30, 2012 Share Posted November 30, 2012 Ah right, tricky shit. Supercharger would be an RPM switch setting? Water Injection would be a boost switch setting - assume you want water injection at high boost? What are you doing with the mitsi ignitor? Are you wanting to run mitsi coils and wasted spark? Does the LEM have enough Aux outputs to do a boost/RPM switch? You could always run the water injection off a pressure switch if you did not have enough outputs. Disclaimer: I've not done a -ZE before but can make shit up... Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted November 30, 2012 Share Posted November 30, 2012 How are you controlling water injection - using a cold start injector or something? Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted November 30, 2012 Author Share Posted November 30, 2012 Water injection Currently its wired up to a switch but can be rewired to a hobbs switch Yea it has wasted spark factory but the ignitors are weird and dont work with aftermarket ecu so the mitsi or a subi one is used Quote Link to comment Share on other sites More sharing options...
vivaspeed Posted November 30, 2012 Share Posted November 30, 2012 So having a read of my LEMV4 manual it would seem that there is only one Aux on a V4 (I thought there were two) - can be configured as boost or RPM (or idle control). It also has a really good explanation about wasted spark setup. Also reading about ZE supercharger clutch control they are a tricky beast - operate when vacuum drops below a certain level. I thought they were RPM controlled for some reason. Must be some literature around on how to set it up with an aftermarket ECU but would suspect it could be done using manifold pressure. The ECU engages the supercharger based on intake manifold vacuum. When the vacuum drops below 8" the supercharger clutch is engaged. The clutch stays on until the intake manifold vacuum has risen to over 10" for a period of 5 seconds. This time delay was added to avoid cycling of the clutch during shifts and momentary throttle transitions. Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted November 30, 2012 Author Share Posted November 30, 2012 yes the car has a icv so i dont know if i still need that also will investigate the triggering could just wire s/c on all the time use boost trigger for water injection and use 3rd injector output for the s/c light on the dash so it works as a shift light Quote Link to comment Share on other sites More sharing options...
