Would have been interesting as an exercise but that mp9 in billybob's car threw a total hissy fit as soon as the cams went in. You could almost not drive the car and it would'nt even rev past 5000 rpm let alone idle. Hence the descision to fit the AFM since one can kind of half ignore the vacuum(or total lack of it) that the cams present.
Of course I also dropped the distributor(that was leaking oil in any case) and put it on wasted spark while we were at it. Will get it back on the dyno for another run once the lambda tuning had a bit of time to do it's thing and see if it looks better at the bottom.
Yeah I have for the following
Stock ABF (Reef and Coast)
ABF with 268/272
ABF with 268/272 and flowed head
ABF with 272/276 , flowed head and other bits
BillyBob did mention that the car went simply nutters , but that can be a whole wost of other issues which just exasperate the fact that the map was out .
Actually , a 16V idles and behaves pretty decently on mp9 , more than pretty decent dare I say.
I have found that on longish cams I can get approx 400 mb on ilde , which is decent enuf .. Fiddle the compensation and correction maps a bit , even the VE map and its real smooth.
