My graph from that day looks pretty much the same as yours does.  I have the silver Auto B4 that was there...  It's nice to know that it seems to be a consistent trend and not just happening to my car.

But i too would like to know how to fix this issue...

But Brendan, yours is the manual,  I've got a slush box remember.

03 model, no pinging according to the guys listening to the motor while running the dyno.  Confirmed my own suspicions that mine didn't ping and had minimal VOD, that's only about 250rpm worth according to the graph, sweet FA compared to some.

Why wouldn't the standard injectors I have be the same as a manuals?  They're the stock black 550's that all B4's got AFAIK, never heard anything different in all my web cruising.

I'll bring the tools, as your's are sh1t.:Derisive:
I think he's got plenty of injector left at that output Brendan. Are you sure that there are no leaks from the newly installed intake manifold?

BTW Brendan, what boost controller are you using?  As mine is all over the place and Billsy suggested on RSLC that I get one, but I've never seen or heard of anyone having one for a B4 - must be blind in my old age and have just not read the right forum posts.

ahh yes.. this explains alot.. I don't have a boost controller, It made my engine and turbo's do all sorts of things.. it couldn't hold constant revs on the free way etc.. and boost spikes! get rid of it!!! I had it set to 17 psi, only for it to hit 23psi when it felt like it..

Mine is done by the tune, the ECU has the boost mapping set high, so the car controls it as per normal.

and with the auto B4.. sorry mate, they are rated at the 440cc... Manuals win again!

edit..

I realise you said you want one, not own one.. heheh,

either way steer clear of them.

and I had a GFB (go fast bits) atomic controller.. manual

just post your ecu to him

What do you mean you need cable?

I meant, unbolt your ecu from your car, post it to kosti, he will put the tune in, and post it back.. ?

My guess would be that the IAM drops when it starts to lean out hence the drop in boost and the AFR.  The standard maps are designed to run rich for safety reasons if the IAM drops low and also it cuts boost back to between 5 and 8.

Full on limp mode cuts the boost to 5psi,  but i think if it get to 6 or 7 IAM then your looking around 8psi boost and rich fuel ratio.

Looks like your car saved itself from pinging on the secondary turbo as these cars are known for not gettin enough fuel when it needs it most.


Thats my thoughts anyway
