Yeah there's no denying ms is the way forward nowadays.. Spose we don't want too many other abf mk2's about, else we wont have the edge..plus I don't think there's enough abf's to go around for every1!!

TBO i'll take back my comment of not much being right with K-jet.. None of my jetted cars have ever had a issue with fueling... My current motor runs a stage 3 head and I know the only real drag is limitations on top end fueling going any furthur than this.  Also MPG isn't as great in a K-Jet compared to Digi.

From results I've now seen, all I read was a standard abf making 175bhp on standard gear and thought yer 15bhp increase. but now seen people getting normal result like 160bhp.

Yer my kjet wasnt fuelling enough for my 9a.

My kjet abf seems to be ok at the mo,the 9a did pink on wot on hot summer days last year though, on the exact same setup on the exact same settings.. It absolutely rinses fuel, but to be fair it is overfuelling. The wur needs doing, and it stinks of fuel from the exhaust.. Going to set the pressures as per the wur mod guide, then weld a lambda boss on and use a wideband to check its ok at top end...it makes soooo much differnce to mpg when hammered tho, and I can't help hammering it.. Reading this back I can imagine I'm going to have probs in the summer, its overfuelling so I've got to back it off, but it pinked on the 9a as it is last year, so backing off the fuelling isnt going to help..hmmm....doh

Yer mine pinked too, dunno what the mechanic done, (retarded it) but when it came back it was slower :( I wouldnt surprised if it was running 140ish lol  as a vts seemed a bit fast along side me! which are 125.

Haha yer I tried to promise myself not to boot it but is impossible I think  :undecided:

If you build the ecu itll costs peanuts if done on an abf anyway. I rekon about £300.

http://www.clubgti.com/forum/showthread.php?t=226056 second graph down on this boys ms is hoping to make 175bhp, about 20bhp other standard, so pretty good. Mine only costs a more as it was done on a 9A.
