is it lean up top? could be pinging for other reasons...
Would be a lot easier to tell if he had a wideband.
They're like $160 jack just buy one and stop being an idiot
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!

Enjoy your blown up motor then. You can join VB242
Trying to fix something not here to lolz
So these are the knowns:
-wastegate is fixed now
-With simon's ecu(s?) it's presumably a dog (any codes?)
-With stock ezk it's fast but pings up top
-lh 2.2 (lawl)
-blows charge out exhaust (????)
So, as it's lh 2.2 and 16v-a combo that I'm not sure ever existed 'in the wild' in the US (let alone turbo)
We don't have a wideband, so there's no telling what the afr's are
What's the base timing set to? how does it respond to retarding the base timing a couple of degrees?
there's no hard data here, so really there is not going to be any solid advice to give. Bigger injectors? sure, why the **** not. other random ecu's? **** it, why not!
Hey while we're at it, let's put a 4 bar regulator on there and crank over the CO screw on the MAF because reasons!
In the presence of data (not hearsay or assumptions), answers will become clear.
valid points (yeah I get this thread sucks. I asked the mods to lock it but they didnt and here we are)
wastegate fixed and everything with exhaust stuff has been fixed
simons ecu runs like dog on my setup - sent him a message - you can read codes? on these
stock 2.2 turbo ecu with turbo ezk - fast but does ping over ~5.5k
timing is set to about 10-12 - runs like dog **** if I retard or add more it runs like ****
850 red turbo injectors
npr intercooler
3 inch exhaust
so yeah whats next
A failing AMM. I have run into this issue several times with 7-9 series turbos. That is why the problem comes and goes. A 780 I bought would run perfect one minute and couldn't get out of its own way the next. The boost gage would be pegged and the car was producing 25 hp at best. Good luck finding a known good 007 AMM to put on there to see if this is the problem. K-jets has a couple of good 007s if you want to try one. If you plan to keep this car, you should buy one anyway while you still can. They are getting to be VERY hard to find in good working order.
You may have a bad connection. That's what I hate about 2.2, no diagnostics. The fact it comes and goes like it does indicates it is something electrical, not mechanical. Waste gates don't fix themselves.
So you're running 315cc injectors and some china turbo at what boost? You could be out of injector at 5.5k when the turbo is making peak boost.
I didn't think anything related to 2.2 learned anything, unless sbabbs chips are different.that was a consistent problem only on Sbbabs ecu. Im just waiting to see what he says
its my understanding that the ezk will do first 1-2 pulls as the base and then adjust accordingly with each on/off cycle and that's exactly what was happening to me
Your injector size is way too small. The 16v head flows more air than an 8v head and you've added a turbo to that. IIRC the stock 740 turbo injectors are 290cc and you've gone with 315cc injectors on a head that flows more and a much bigger than stock turbo.
You're wondering what the issue is.....
haha.. i never thought that easy... this is so how much does stock support...
