ls/v question

[jealous1shateric]

Ok here's the scoop
my boy has a ls/v
b16 head ctr pistons
thing runs like a single
timing is correct
just need some insight on what can be wrong.
im tryna get my hand on a compression tester
lmk

What ecu is he running?

[burim]

i got a fully built b20v and its runny like shit cuz it needs to be tunned i got an ecu from my last built so i can brak the motor in but deff get it tunned

[jealous1shateric]

we have tried my p28 with chip and a stock p28 same thing i don't think its an ecu issue at this point

well we got stock cams and what not so i dont think its ecu

i tried g/l with the car

whats ignition timing set at

Burim thats the worst thing to do..... Rick It still could b e a tuning issue. CTR pistons on a ls/vtec should not even see a stock or incorrectly mapped ecu. It has way too much compresson for that. Also, try to find more agressive cams too.

[Stanley]

get a nice set of cams and tune it.

http://www.ff-squad.com/technet/cr-calculator.htm way to high for a stock ecu. At least try a type r or gsr ecu and see how it runs.

[jealous1shateric]

the p28 was tuned by dave with a similar setup idk at this point

yea all these comp calc all say diff things so idk right now

[kbrown!]

if you have a header, and intake manifold and 2 1/4 exhaust then id try checkin the compression to eliminate that as a problem. if not try a new tune. if that dooesnt work i have no idea. just make sure you've got good compression and i/h/e to help that flow.

[daveedd357]

similar don't mean that it is right

[Slim]

Hmmm... could be as simple as one of your spark plugs connected correctly. If not that then definitely it's a tuning problem.
