help with fuelly map after installing new injectors
 

Hi all,
I've just fitted some new low imp 460cc rx7 injectors.
The car was originally mapped by owen developments (a uk based tuner with a brilliant rep) on 320cc injectors so to adjust the map I just reduced the injector opening times all by 43.75% however now it is running really rich and my fuel mpg is very poor... also the afr occilates quite alot and wont idle at a set stoich ratio... it bounces from high 12s to approx 22 then back down again (measured with an LC1 wideband).

I've adjusted the deadtimes using some of the info from the guys on here but it doesnt seem to have helped.

Just wondering if you guys can take a look and see if there is anything in here that looks odd to you.

Cheers
Tom
