PumaNoob said:For the VVT you'd have to run the MS alongside the standard ECU to get the VVT working correctly, like I did with my green puma turbo. The good thing with the puma ecu is it will still run even if its not controlling the spark or fuel!

I see but you couldn't adjust the vvt with the megasquirt to help it come on boost better then peak higher aswell it would be set to standard puma vvt settings ?

Nah, megasquirt is a very good bit of kit, but its also very basic so it wont run the puma VCT. It would run it like a V-Tec, either fully on or fully off. The only way you could adjust it slightly would be with cam timing, and then your still limited to a specific band, youd move it up the rev range or down. There may be a way around it, but not that i know of.
you'll have to look into cam selection, lift and duration for the 9k rpm engine, makesure you have the clearence. Id also check that the VCT can sustain the pressure of those revs, its only held advanced by oil pressure, and not designed to work higher then 7200rpm. It may be ok but its worth a check. It would be good to put the VCT more gradual on that engine, then you could get a more specific cam, at standard settings, your going to get no advance between about 3500rpm and 9000 rpm, so its sort of pointless having vct as youll spend most your time on a track in that rev range.

paulob1 said:its ryan that has committed me keeping it active and I agree with him, with the vvt/ vct it will be more driveable at low rpm...he is using the pectel ecu I think arent you ryan, you said that could do the vvt too...it may be worth a look but am happy for now with the megasquirt...with all my projects i am short handed and I am buying myself four Subarus, turbo leagacy 180 bhp, two twin turbo 300 bhp cars and one wrx with 280 bhp...the 280 car is going to be my winter hack as i wont have my pumas ready this winter...other than turbo nitrous and pumaspeed...419 is getting welded this month and will be back on the road in std format as her engine is so sweet....088 is getting the f3 engine, and that work will start next week once i have collected the engine...bad news is customer work is on the up again and we are busy again so time will be short.
AM going to stick a turbo on nitrous too aiming for just 200 bhp without nitrous and a further 25-30 bhp with, thats enough for that car...
son getting involved with the subaru buggy upgrades so that should help a lot...buggy plan though includes using the std 5 speed subaru box and two wheel drive...should work really well and i dont have to spend a fortune upgrading the four speed bettle box which is a real yawn box...mind you makes the car safer as it will not allow the car to go much above 100 mph and buggys should not be going much faster than that...
PumaNoob said:But that's the point, to utilise the VCT properly with the high rpm's, you really need to have full control over it, but the MS doesn't have the capability to do that. It will be fine on the turbo puma as you won't be revving it past normal rpm limit.
The only way to do it with the ms as a piggyback is to reprogramme the standard ECU too. If your going to go through that you might as well just go for the pectel ECU from the start.
