Help needed please...

I have bought a 123 tune (usb) distributor for my car as the one in there is all wrong for the engine and i was wondering if there are standard maps available anywhere for different setup just to get the ball rolling.

It came with 2 maps installed but i have no idea if they will work.

I can install it and probably get it running,i`m competent with a laptop but have no idea about vacuum and settings etc.

Engine is 2.5 with ported and flowed head,matching inlet flowed to head and fitted with twin HS6.
Mike Randall 6-3-1,TR5 cam.Compression ration is 10:1

It made 172 bhp on a rolling road when installed a couple of years ago.

If anyone could offer any advice it would be appreciated.
Steve

Steve,

This is the ignition map from my PI.  It's an Megasquirt map so gives total advance only (whereas I think 123-Tune shows separate curves for mechanical and vacuum). However, the top line (100 mBar line) effectively shows the mechanical advance and with a bit of cunning and an excel spreadsheet you can probably extract a vacuum curve of sorts, though I don't think the 123-Tune allows the same degree of flexibility.

Very cool Nick 46 deg full advance. Mine with such a high CR I could not get near that best I could get was 40 deg

Engine never goes there anyway, or only when you are right off the throttle.  The sort of area I reckon you're thinking of I've got about 40º too......
