Z20LET Map with wasted spark external coil

Hello all,

I am a long time user of DTA ECU's and have been using them on many atmospheric applications (BMW E30 M3, Opel CIH 16V, etc.).

Now I built myself an Opel Ascona converted with an Z20LET from a Vauxhall VX220.

The engine is stock with stock injectors, it has a Jenvey Turbo Plenum, big Intercooler and a slightly enlarged compressor wheel. Furthermore the turbo charger is stock.

I hooked up an S60 which needs mapping now.

My request is: does anybody have a base map for me to start with. Got the engine idling on a C20XE map but I would like to start with some proper and suitable turbo maps and settings.

Thanks in advance, Henri.

Hi, do you still need this ?

My used s60 came with a VX turbo map, so may be of use? I haven't run this map so very much buyer beware, but happy to send it if it might be useful.
