Title: Aftermarket boost solenoid hooked up to N75 harness Post by: orienz on August 06, 2011, 01:24:14 AM Can i controll some aftermarket boost solenoid with ME7 ECU? Did anyone attempt this? Idea comes from Mitsubishi/Subaru people. They hook up "better" boost solenoid to factory harness and use ECU to control it. This would eliminate the need of EBC.
Thanks for any input. Title: Re: Aftermarket boost solenoid hooked up to N75 harness Post by: orienz on August 06, 2011, 01:25:32 AM By the way I have something like this:

It's made by Mac. It's supposed to be good.

The MAC will most certainly operate at a different frequency then the original N75, the pintle reaction times will be different... so it's not going to be just a pnp setup. Title: Re: Aftermarket boost solenoid hooked up to N75 harness Post by: orienz on August 07, 2011, 11:41:35 AM Any starting points? This is getting it to work under Eurodyne Maestro. Maestro has 4 maps that control "boost".
Boost PID Boost duty Maximum VE Maximum VE under knock They are labeled this way so I guess I should play with Boost PID and Boost Duty, right? While I do get what Boost duty is I have no idea what Boost PID is and what it does.

Can you adjust the freq value in the flash? I would like to think Bosch would be smart enough to provide a variable that can be adjusted just in case of a product revision or using the ecu on another system all together?

Title: Re: Aftermarket boost solenoid hooked up to N75 harness Post by: orienz on August 11, 2011, 12:25:40 PM hey julex, no man I understand what it is...approximately but I just don't see how ME7 is actually controlling it. As far as I can tell there are like two tables (at least in Maestro) and there should be 3 different variables (p,i,d) but there is only one. Another table is duty cycle...i get this one.
It's very confusing... |
