Hi everyone,

Firstly sorry if this is in the wrong section, its a bit of a weird problem I'm looking to solve.

I've got a 2006 Vivaro with the 1.9 F9Q 762 engine.

Its a frankenstein of a van. At some point in its life before I bought it its had a complete lump fitted from a laguna. Mechanically the same but runs the gt1749v turbo. I bought the van as a cambelt failure and that's where the fun began :lol:

It's an ex private ambulance and from what info I can find originally it ran a garrett gt15 in a low power mode - wastegate plumbed to pressure side with a week actuator spring. The ecu has no input relating to turbo pressure or solenoid control. There are no wires in the loom for a map senor or n75 valve.

Its fully rebuilt the engine and I have kept the gt17 as I fancied the benefits of the vnt. I'm running a stand alone vnt controller that works really well. Currently set to 1 bar until I can sort the fuelling to match anymore boost.

Would someone please be able to look at my ori file and explain what turbo maps are there, are they in use/diabled?

I've been reading the edc15 tuning guide and want to add some more fuel to the extra boost I can give it but don't want to waste my time if the ecu is going to limit fuel based on turbo maps that have no input to use.

sorry for the essay

Cheers Ash

Anyone please?

Ok so first post not that successful with replies. I've paid to have my file tuned with the hope of comparing them in Winols to try and see what maps are where but still lost.

Would some please give me a clue, winols suggests 49 potential maps but only 9 have been changed on the modded file.
