bye bye DSM, now i have around 3k-3500 for a new car.. what to buy...

anyone have some free time to help me with link? car breaks up bad under boost, tried adjusting timing and fuel , neither helped, maybe an extra set of eyes on my log would help

I know nothing of DSM's for say, but the words "breaking up" got me to thinking about spark plug blowout .. Jus sayin .. Plug gap .. Coils .. plug wires .. possible causes ..

DEF try plugs firt...they might be fouled or gap too big and blowing out the spark. gap to like .24 and try that. of it works maybe go out to like .25-.26 and stop there.

send me a log i can look at it. and my Spic can take a look as well. he's pretty good with that ****.

email me HaveBlue83@yahoo.com

new plugs, bpr7es, gapped at .028 , plug wires look to be newer but i may try them, def think its tune related since it never broke up this bad before i went to link, it would just knock run rich in boost

i emailed the log

my spic says that tune needs work. he said he messaged me and a base tune file is on the way, should help your issues if the car doesnt have any Boost leaks and turbo/engine are ok.

you were lean, and either a boost leak or turbo issue as well from what he saw. said it was JACKED up.

yea ill be checking for boost leaks today hope i didnt get another hole in my coupler =[ its so close to the fan shroud it rubbed a hole it it once before, i was hoping i had trimmed enough off to keep it from hitting again

just did a BLT, ould only get up to 15psi since my tester kept blowing off I need to make a new one , but up to 15psi the only place air was coming out was the breather on the side of the VC and my dipstick tube, I still need to pickup a new pcv valve

Get a slim fan...they're cheap!

^^That is suspect for bad sealing rings. your combustion chamber is pressurized and there is air seeping past the rings, into the crank case and it's coming out the dipstick. have you noticed the dipstick pops up after driving it?

also, i sent you an email last night...the tune is way off. you are at 12.5 afr, when you go WOT, then you lean out to 13.5. the timing also drops from 20 to 8 during all this (most likely ECU pulling timing for the lean issue) and then it knocks. you let out and then went WOT again and it continued to knock. I would suggest NOT boosting on that tune and to DEF get in that tune file I sent you ASAP and let me know how that works for you. it should stop the lean issues and knock for the most part, but the crankcase pressure is a mechanical thing not tuning. my spic (who sent me that file for you) said he can work with you more for a tuning fee if you desire. just email me if you want to do any tuning and I can get you setup with him.


I miss this stuff lol.

he also needs to know the turbo/inj/etc setup because he said your airflow numbers arent matching up, indicating a leak or bad turbo in the mix.

I did not boost anymore after I took that log, the only time it went to 13.0 was as boost was building, I put his "base" tune in and it still knocked, no boost leaks like I said and Im 99% sure the rings are fine but ill do a compression test to be safe,it only as ever blown the stick out once.

to add though I did find the setting on my translator were all messed with so I zeroed everything out and had to make major changes to the MAF curve, I put the new wires on and now it no longer breaks up but knocks under full throttle, I took a log of a short pull when it began to knock I can send to him if he wants

not much more money to spend and I don't think I can get a slim fan before the rental, but I don't have any boost leaks now so im not worried about it yet

yeah send it to me. i will link it to him.

Anyone want to help me chase down a phantom electrical short that keeps smoking my 30a ignition switch fuse? Lol

not sure if 2gs have them but theres a pin by the battery on a 1g that can be used to power up the fuel pump and i accidentaly touched mine to ground and blew the ignition fuse, maybe check that?

stover......can you do a leakdown test of your car and post up the % leakdown in each cylinder? your car either has a MASSIVE boost leak or your rings are shot, just thinking offhand with what I saw. you are doing 49-176 lb/min airflow WOT and the boost goes from -4hg wot to 13psi. there is no power happening....and you need fuel, spark, and compression to make power. never seen a log that looks like that.

those numbers are not accurate , my boostEST is not even close to my actual boost curve, the boost EST is still climbing while im already in full boost, and my full boost of 18psi is clearly higher then the 13 psi it thinks im making

I have no access to a leak down tester right now but compression test shows

cyl 1: 120
cyl 2: 115
cyl 3: 115
cyl 4: 125

so a little low but not terrible I don't think , I mean the motor is unknown miles just has a new headgasket , tbelt and arp headstuds so I didn't expect a lot from it

Try adding a little oil to each cylinder and see if the readings change.

Try a bit of marvels mystery oil in case the rings are stuck from sitting. Perfect compression is 160 when hot. Anything in the 150s is good. If you need the phone number to the actual owner who did the work and knows the motor just let me know !

Had that happen to a guy that owns STN in pa. Compression was 50-60psi and then went up to 155-160.

If the rings were bad I don't think the owner of the motor would have done a new hg , arps, water pump , new head etc .

That is below serviceable engine limits. Thats part of the reason......now pull your intake and check the turbo for play if you would.

Service limit is 135, warming it up usually only makes a 10PSI difference or so which means you're bellow the service limit anyway.
