On mine I used D-jet so I couldnt specifically say other than its my understanding
that it should be EASIER to tune a slightly modded L-jet motor. Basicaly Fuel presure, Flapper gear and fine idle screw (I'm sure someone will step up and tell me I wrong and full of (IMG:style_emoticons/default/stromberg.gif) (IMG:style_emoticons/default/biggrin.gif) )
I bought a set of KB 96's and Hasteing rings from Raby (with the correct Pin height for the 1.7/1.8)
the only other thing I did to mine was rebuild a set of 2.0 heads slap on the 2.0 FI 2.0 SS HE's and a Bursch Exhaust modded for a WB02 sensor (IMG:style_emoticons/default/thumb3d.gif)
Geoff used his LM1 to tune the MPS and its a kick (IMG:style_emoticons/default/driving.gif)


is the only difference with 1.7 and 2.0 d-jet f.i. system in the computor programming? if you where to put a hotter cam or increase c.c.'s on a 1.7 engine with D-jet (or in this case a hot 1.8 L-jetconverted to D-jet), would a 2.0 computored D-jet system give a tunable air/fuel for such a set-up? how about tweeking the regulator to increasing fuel pressure? i've heard the stock 914 injectors flow better volume than many other injectors under increased pressures.
