KONIG's Turbo Thread
this past weekend greg installed new OEM plugs, wires, and coils in my car and got a oil change. my original spark plugs were horrible, corroded, and even greg was surprised my car ran as well as it did. this was the first time changing all those things, and im at about 43000 miles now.
anyways, the car is still running great and even better now with the maintenance i just did. still pulls smooth all the way to redline and AFRs always stay in the 11's. hope it continues this way and ill keep you guys updated if anythings changes!

It is really good to hear that others are enjoying the Turbo kits, I hate when I hear horror stories when things go bad.
Happy Boosting and glad to hear she is still running strong!
is it normal for boost to only climb to around 6-7 when in first and second at WOT, but in 3rd it creeps up to around 8 then in 4th 5th and 6th it goes to about 9-10?
i saw 11.5ish psi on my boost gauge once and that was in fourth gear at WOT. the AFRs stayed in the 11's though...

update:
i havent had annnyy problems whatsoever
until now...
so i went to fill up on gas, and on the way home decided to give it some gas to get into boost. i was in 2nd gear and gassed it hard to get into boost, and around 5 to 6k rpms it felt like i hit a wall in my power and the sound it made was like fluttering air. AFR's stayed around 11.2 and boost was at around 6psi. i was able to reproduce the same feeling and sound again but around 6 to 7k rpms. as soon as the problem happened a CEL came on and stayed on and the traction control light (little car with squiggly lines) came on and stayed on.
i turned car off and back on and the CEL was still on, but the traction control light went away. car still drives fine out of boost and even with some boost it drives fine, seems to only happen when i give it a lot of throttle.
The CEL code is PCM PO103: mass or volume air flow circuit high input
has anyone had this CEL before?

i tried to reproduce the problem while datalogging and i was able to, but i cant upload my datalog so here is two snapshots of the datalog where i am pretty sure the problem happened...boost did not go over 7psi on my boost gauge during any time.
I had that CEL twice already and yes you will feel like you hit a wall! I have been trying to find out what the problem was for a long time now, but never really successfully did. But I suspect that there might be water droplets inside the MAF because I got the CEL twice on two different moist days. I also believe that the AEM intake does suck up moist and maybe even water because I found dried water spots in the pipes.
After I reset ECU, the car ran fine with no problems at all. The last time I experienced this problem was 2-3 months ago. I guess you can also try cleaning your MAF too.
Are you using the dryflow filter on your AEM intake? Because I am and I might switch it to K&N to see if this fixes the problem.

interesting, at least it doesnt sound like a deadly problem...
well im going to have to be removing my MAF tube soon to weld the nipples on my AEM intake (dam rubber caps keep drying up and cracking) so ill clean the MAF and make sure theres nothing wrong with it.
its not really a moist night tonight, but i did just wash my car earlier today...no water got on the engine but i bet the AEM filter was soaked. hmmmm. no more driving after washing my car!

Hm..
I too have this problem recently since i got my intake ceramic coated, but mine usually happens when starting up the car and it would get IAT voltage too low or MAF voltage too low.
I experienced this one time while WOT and the car stalled when the CEL lighted up.
I think I messed up the MAF connector when i reinstalled the intake.

weird...i dont think i damaged anything on my MAF, hasnt really been messed with since we installed the turbo and everything.
im gonna be driving it today, lets hope it doesnt act up!

people use the AEM intake because it comes with a useable MAF tube that works well with the accessport to get tuned. theres some pics of the install earlier in the thread...
Sounds like your MAF got wet but your grams/sec weren't that high. It would be good to also log MAF voltage as well.
On a side note, I saw in those screen shots you're using Vista, can you connect your AP handheld in Vista? Mine keeps saying it's missing drivers....I have to load maps and stuff off my XP machine
