Rb25Det Carnt Get In Below 20Degrees Timing?

[nisn]

hello' yes problem is it runs 1000rpm.and connot,no mater what i do get it below 20 degrees timing? any ideas anyone. thanks. .

.

)its also cutting out over 12psi boost. tryed stock ecu and another that sopose to be mapped for higher boost,and cuts taken off. but but ecu's seem to run the same

.have t04,but shouldnt be that causeing probs with to much air.(

front mount

greedy intake

t04

38mm wastegate

3'' way throught

pod

manual.--- - with auto ecu-and manual mapped ecu--have mapped 1 in now.

bleeder

fuel reg

thats bout it i think for mods

You need to get the idle correct. There should be a tutorial somewhere on how to adjust it using the screw in the AAC valve.

Then make sure that the timing light you are using is not doubling the reading when you are checking base timing. Best to go "old school" by inserting a spark plug lead between #1 coil and #1 spark plug, then measure the timing off the lead.

the AAC valve screw is right in.. if i wind it out a little it revs to 1500rpm. .no mater if i turn cas.it stays on 20'. ...could cas be a tooth out??? i can put the timing on -15 in an active test.from conzult or somthing sounds right. but as i carnt burn it to ecu. it jumps back to 20. in saying that. when on -15. the conzult reads 10 degrees. some say auto motors came out running 20 degrees, but shouldnt mean i carnt get it to 15 somhow

Are you sure there are no air leaks anywhere?

Are you sure there are no air leaks anywhere?

+1

Intake manifold/plenum/throttle body gasket, vacuum line off/leaking, dud brake booster etc..

If not:

-A scantool will help (ie check what the IAC is doing, if the car's staying on cold start and holding the idle too high)

-Check your throttle body isn't jammed/being help open.

-Dodgy MAF?

Are you sure there are no air leaks anywhere?--)--------- yeah to me that sounds the prob,i will check today.

Intake manifold/plenum/throttle body gasket, vacuum line off/leaking, dud brake booster etc..--)----------------------------- will do proper check today.

-A scantool will help (ie check what the IAC is doing, if the car's staying on cold start and holding the idle too high--)-------------------------------what is IAC sopose to be reading at idle ??i have a scantool..

-Check your throttle body isn't jammed/being help open.--)----------------------------------------------will also check that today.

-Dodgy MAF?--)----------------------------could most likely be-it was throwing maf connection code, and makeing motor just stop random. till i earthed the E to the chassis hasnt really done it since, but still could be stuffed..

thanks guys appreiate th help ill give them a go and see what happens. also have nistune but no ECU yet. is there somthing in the program to look for tht might help,such as levels of sensors, everthing should be basicly stock.

ok i think ive sorted air leek found 1 round addaptor plate to throttlebody, prob now is it cuts out on boost random boost levels. i will try mates coils, but any ideas way it would cut at low boosts and motor surges when pulling up,like geting way to much fuel.

[nisn]

got it pretty good, it just cuts out over 5-6psi. any idieas. maf?
