Hi Everyone
I recently got my car back from the tuner, and I've been told that my car can only be driven after warming it up for 10-15mins, as the new cams I have put in are not pulling enough vacuum to run the car until the car is warm.
Here are my car specs:
1993 RZ
Stock Automatic (a340e)
Kelford 264/272 Camshafts (put in at TDC)
Stock ECU with E-manage Ultimate Piggyback
Munro Stage 4 Highflow Twin Turbos (Stock twins high flowed)
3" FMIC
Walbro 460 Fuel Pump
Sard 650cc injectors
It's Jap spec so it uses a MAP, not Maf sensor.
Can you guys tell me if that sounds right?
My car struggles to stay on sometimes even whilst warming up.
My tuner said its because it is Auto, and the cams I have put in with emanage do not work well together.
He said the new cams need to idle at 1k rpm, but the stock ecu is trying to idle the car at 650rpm.
He has tried to raise the revs with the emanage on startup, but the emanage and stock ecu are fighting against each other to keep the revs up. But when the car is warm its fine and won't shut off.
Is this a known problem with larger cams and piggyback ecu on auto ?
Does anyone know how to get the car working without having to wait 15 minutes to drive it every time, and it turning off when I put it in drive and try to accelerate?
Is there a setting in Emanage ultimate to raise the revs that maybe my tuner didn't know about? Someone mentioned TPS and voltage settings in emanage, but don't want to play around with anything unless I'm certain of what I'm doing.
The tuner said we can manually adjust the TPS screws, but then the car will always think I have my foot on the throttle, and will not gear properly. (it's auto)
If anyone knows of another way to get these cams working with emanage ultimate and auto tranny, I would really appreciate any help.
Thanks
