Hi Gents,
i took the plunge and wired up a Haltech Elite series ecu.
The good news is the car starts and runs without Maf
Though there is a couple issues
First is an intermittent issue with the crank sensor not sending a constant signal to the ecu (ie the Haltech shows the signal from the sensor as if it is going "on/off" which is causing rough idling and running from the fuel pump.
Using an oscilloscope, we can confirm it is reading correctly. So the sensor is working but dont know why it is doing what it is doing.
Anyone else experienced this?
second issue which is a weird one... Somehow it is losing spark to one coil pack. But the weird part it changes. Ie sometimes cyl 1 spark will stop then it will kick back in and cyl 4 may stop. Then kick back in and then another different one may stop. And then for a short few seconds she purrs beautifully on all 5 until it starts missing again.
Fustrating to say the least cause we cant put a finger on it but the most important thing is it starts and runs with the Haltech ecu.
A rep from Haltech is coming in to see if they can get to the bottom of it but was hoping someone can shed some light on it.
