2.9 Engine has ALL the snesors OBD2 requires If the 2,9 is from a UK Corrado, there will be no EGR to worry about. -
If it is OBD1 and the lambda probe signal isnt plausible, the sensor will be ignored and the ecu will add full fuel trim (+25%). If its OBD2 and the sensor signal isnt plausible, the sensor gets ignored, and the ECU runs open loop fuel table, ie no fuel trims are added.

You will need a 19mm core plug to bung the EGR hole in the front of the head.

EGR will come into play here. You will need a 19mm core plug to bung the EGR hole in the front of the head.

Standard metal multilayer gasket will take 83mm no problem.

All VR6 'boxes are the same

sounds likes its more likley to be a CV joint, or a diff rivet.

Get someone to lift the pedal up, pop the cap off the firewall in the engine bay. poke a screwdriver through the slit, and pop the end of the cable off.

I just looked through your engine install pictures and see you have a distrubuter, just as you replied. Unsure on the extra pin, it could be an air temperature output.

Help converting my 2.8 vr6 engine to a 2.8 vr6 4 motion
UnitedMotorsport replied to shawn25's topic in Engine Tuning
Have the immobilizer removed from the ECU, and install the MK4 loom and ECU. itll run perfect. -
EARLY OBD1 as in the 6 pin maf. It is a misconception that all 2.9's are OBD1. Altho all corrados were as far as we know, Which config do you have? coil pack? 6 or 4 pin maf?
-
It'll run fine, just not make as much power if you have an early OBD1?
-
Theres many reasons for using multiple maps, Watermeth injection for example. Currently working on the MK3 VR6 RHD kit.
-
You can also have switchable maps in the standard ecu, but its certainly not needed to handle diffrent boost levels.
-
In simple terms, yes
-
All possible, and no need to change the maps.

Your gearbx will bolt right up, use the VR6 clutch and flywheel. -
A fuel pumps pressure is regulated by the FPR.
-
Fuel pressure at the fuel rail with a 4 bar FPR should read 4bar with the vacuum pipe pulled off at idle. It should also be 4bar at WOT under FULL load.

They're the same design, Peloguins will honour your claim if you have a warranty claim, Quaife will not.

Completely agreed that C2 has a vested interest here, But we are not PUSHING people into using it, We dont mind answering questions or offering advice. We map standalone ECU's too, so I know entirely both sides of the debate! DTA, Emerald, MBE, Motec, Pectel, etc, I've done them all. If i was to choose one to run an engine i'd choose Pectel. When you say "90% of people dont understand standalones," I would agree with you, but I'd also like to add that 99.9% of people dont have the 1st clue about Motronic ECU's. To say that the OE(Motronic) ECU wasnt designed to be used with boost is a falacy.

This is gonna turn into the standard management vs standalone argument thread, I can see it coming. Our 42lb OBD2 canned software will run on any correctly setup 12v VR6, and it will run perfect, idle, fueling, ignition, at any altitude at any natural ambeint temperature. Currently this has produced a maximum of 424hp to the wheels. The are limitations to the standard ECU, that is correct, but there are limitations to what people term 'A Standalone ECU' too. To us a standard OBD2 ECU is a standalone ECU, We have control over everything that is in there. Idle control for example. C2 software a

Is your car OBD1 or 2?
