Tip in?
so the tuning begins in earnest, and already I have a question....
when just idling and blipping the throttle, the car stumbles really badly, after that it revs cleanly...... what do i need to adjust?
I've datalogged a few drives and calculated a VE table using megalogviewer (with a NB EGO sensor...) and i've tried doubling the fuel in the low load areas, but it's made no discernable difference. Am I editing the wrong thing?
Thanks!

Mine does the SAME exact thing. I havent had chance to try it yet but have been told to work on the Accel Enrichments.

You really, really need to get a wideband. Save yourself from countless hours of guesswork and desperation. An LC-1 is $199 and works wonders. Other than that, your acceleration enrichments are propably too much (too rich) and you need to get 'em down a bit.
Acceleration enrichments are two pages: Accel decell settings and Acceleration Wizard (or something like that), they are on the same menu as the VE Table and Exhaust Gas settings.

Don't just confine your work to the acceleration enrichments. My car is running very small acceleration enrichments (ie around 0.1 mS at 1500 rpm with the rpm acceleration enabled) and it drives like factory.
Make sure that your VE table gets most of your attention.

On your first tuning sessions, you need the "egg-under-gas-pedal" approach. Imagine that you are driving on snow/ice. Don't suddenly press the gas, use slow, smooth movements so that you don't trigger acceleration enrichments. Also, the light load/low rpms will generally take you more than half an hour to get them right. So focus on that first, then mid rpm/loads, high rpm/loads, accel enrichments, idle AFR, warmup/cranking enrichments.
I did mine in that particular order and I am very happy with the whole process and the end result .
