anyone running cosworth cams on a flash with out issues? or are you using and ems. like aem or vpro?

 

We have tuned many on stock ECU and cosworths cams. Stock and aftermarket springs and retainers.

 

We also have 10 sets of MIVEC Cosworths in stock.

 

well one of my good friends Evo 9 with cosworth cams, gt35r meth 35lbs.

we can't seem to get it to run right on a flash. tuned by a well know tuner here.

it breaks up when shifting at the track. on the dyno in a specific gear it will make a pull fine no problems at all 550whp all day on a stock bottom end.

but at the track 2nd to 3rd up shift it just breaks up and falls on it's face.

 

Find a new tuner.

We have no problem tuning 35R on meth and cosworth cams 30+psi on stock ECU and valvetrain to 8021rpms.

Real tuners tune for real world conditions and not for a sheet of paper.

 

i love my cosworths. when my car is finally finished ill post my dyno plot! still got to have a bit of fun so far and the car pulls like a train. low end has massive bawls and the top end dont quit! not even dialed 100%. more like 70%

 

my friend had cosi's in his 9 w/ no studs and stock retainers, springs etc...the car pulled really nice on a dynoflash, im doing the same next week

 

from what ive seen on our dyno, the gsc cams produce better area under the curve and torque than the cossies... but thats just what we've seen...

I believe that you won't see nice returns until you upgrade the turbo. Most stock turbo 9s can't hold boost past 6k. Cams on a 9 should be an after turbo upgrade mod.
