ignition timing 22 degrees at idle

[absz]

checked timing on the car today and its at 22 degrees vs 10 which it should be? thats with e1/te1 connected together in serial port. idles seems fine 650/680 rpm the engine seems a bit flat in lower rev range.

any ideas whats pulling the timing.

STOCK ecu unit fitted with apexi f-manage to control 650cc injectors.

hks 264/256 cams running t60-1 turbo

Altering perceived air flow figutres to the ecu moves the timing map too, so you see ignition changes. They don't tell you that... They wouldn't though, would they?

[Kranz]

Is there any cure for this CW?

 

I'm guessing that the lower air flows that the f-manage is making the ecu see makes it advance the timing more to compensate for the lower percieved flows?

 

Any simple way of altering the timing map or is an E-manage ultimate the way to go?

[Chris Wilson]

AEM, Motec blah blah, to do it right you need a standalone.

££££ then??

 

How much to do it wrong???

right, checked supROs car using the same digital timing gun i have and its showing 22degrees on his car as well ? so either i have a dodgy gun or the pick up wire ( green wire on igniter pack ) is not a good reference point for No1 cylinder.

 

CW after market ecu might be a possibilty in the furture when i can afford one:taped:

only certain guns work on 2JZ, i forget which types always read higher ...
