Yeah I dont think that will work well without the main TPS assigned to the sensor that is on the ITB's. Accel enrichment, lockouts and delta's for many functions like knock control etc all require TPS. There are plans to add a generic H-bridge control function to the ecu and I have just started on documenting it so you could consider it in-progress now and I think it shouldn't be a major job to add from what I have written so far. I dont want to make any promises on behalf of our firmware team but my initial feeling based on similar jobs and the workload I know of at present, it might be available in a month or so.
Otherwise you could probably find a robotics/hobby motor controller that will take a PWM aux and convert it into a CL motor position control.
Correct, you only need enough ground pins connected to cover the max current with adequate voltage drop and heat. High impedance injectors are usually less than 1A each so its usually Auxes, DBW and Lambda that are the bigger considerations.
Thank you Vaughan
this morning I had a play with the test calculator in PcLink and think I understand now.
I have always thought that it was just filling in the opposite gain / multiplier..
