Evening, Vas.

Hi, Dave.
Thats my working week done.
Man, I am stuffed.
Time to take it easy.


Sup?
if its not to late to ask.

I am NOT a happy camper, nope, not one bit.

Finally got the GTS back after taking freakin 3 months to do the heads, costing me almost 10 grand and its running rich and hunting at idle. Mech says the other GTS's he did GT cams on did the same thing and was fixed by using the Shark Tuner to tweak the fuel maps. I got a shark tuner so no problem.

Early Sunday morning I plug in my laptop thinking it's just a quick tweak away from burning up the tires at the autocross. It's so rich the computer is leaning it up as much as it can to run an AFR of 12. I tell it I have bigger injectors which should reduce the fuel significantly, and NO CHANGE. I have an adjustable fuel pressure regulator so I drop the fuel pressure significantly...NO CHANGE. I'm confused because either should have done SOMETHING. So I pull the pan off, pull out the sideband O2 sensor and do a free air recalibration. Put it back in and NO CHANGE.

Totally frustrated I upload stock fuel and ignition maps to the ECUs and adjust the fuel pressure to what I think would be as close to stock as I can without a gauge. ONLY while reaching the fuel pressure adjustment on the back of the motor my right arm is laying on the intake. It feels warm but not HOT. Well, I burned the &%!! of my arm. About a 3 inch diameter spot. Blistered and big enough the blistered skin sluffed off while I was holding it under the cold water tap. Looks nasty, but doesn't hurt. Been keeping aloe burn stuff on it.

Anyway, take car to local mechanic that installed the Shark Tuner and Wideband. I assume the wideband sensor is either shot, or settings are out of whack not knowing how long the wideband controller would keep it's settings with the battery disconnected during the cam job. To get the Shark Tuner working before the cam job my mech somehow killed 3 LH Programmable ECU modules, PEMs. After the 3rd PEM, Shark Tuner guys sent a known good LH brain. It seemed to work fine so I spent $500 on a new LH ECU brain. Well...Today instead of diagnosing an obviously bad O2 sensor on the wideband my mechanic tried to upload the fuel map he had made when tuning with the FIRST PEM HE FRIED. Guess what? The file fried the PEM?!? Seems that every single PEM that died, he uploaded the same map file. &%$#!!! freaking ^%$#@, why would you keep doing the same thing. I don't even know why the #@!! he tried to upload the stupid file, it was obvious the problem was being cause by the wideband and no amount of tuning would correct or even change it. In fact, I had just pointed out to him that the car idled great when you first started it. Right up until the wideband warmed up and started sending it's signal then it would go rich and start hunting.

The Shark Tuner guys found nothing wrong with my old brain and have told me this is the last PEM they are going to replace, and I specifically am to never ever upload ANY saved map files. Oh and to fix the Wideband and NOT the Shark Tuner. Grrrrrrrr.

That sux, Stick.
I hope it ends up an easy fix.

Bummer. Make sure to keep the burn exposed to air as much as possible. Pure oxygen would be better. I had a bit of a stint in a burn ward.

9 minutes until my parents are to leave LHR for LAX and not a word. I hope they made their flight.

[RKDinOKC]

Months last fall and winter trying to get the car running right, and $500 for a new brain all because he keeps uploading the same freaking bad map file. Aaaaaaaaaaahhhhhh.

Also think the mechanic that did the cam job must have somehow farkled my O2 sensor and it didn't need tuning, it needs a new O2 sensor.

Was thinking the same on the sensor.
Stick, have you checked the crank sensor?

[RKDinOKC]

Keeping the arm in the air and above my head as much as possible. Only putting aloe burn stuff on it. No pain or swelling, but this afternoon it looked kinda reddish green and this evening its looking kinda gray. The aloe stuff seems to dry it out and tighten it up.

Try and keep bandages off as much as possible, sleep excluded.

Parents should have left the gate. No word.

[RKDinOKC]

While had the motor out and apart replaced the MAF with new recalibrated one and new hall and crank sensors. Everything that looked aged (some things like knock sensors were done a little over a year ago when I did an intake refresh), that's why it cost $10,000 for the valve job.

Also pulled the pan and checked the crank and rod bearings.

[vas930]

If you can check to see if the new crank sensor is working, do so.
If you still have the old one it may be handy.

[RKDinOKC]

No bandages yet. Sleep with arm above head burned area up.

Took a bunch of benadryl.

I know it's not really the same thing but looks kinda like the places that wouldn't heal on my brother legs that had MS's and in a wheelchair from water retention and swelling.. They ended up putting a real thin gold foil on it get it to heal.

[RKDinOKC]

The Shark Tuner interface has monitor screens that display all the data the ECU uses. There is a screen that gives the status of all the sensors including temps, MAF, throttle position, crank, hall, timing values, and knock sensors. Everything is green.

If your skin came off, that's pretty much a 3rd degree burn. Nasty and will get worse as it heals. I cut very thick layers of dead skin from my hand as it healed. There is a good ointment to put on it, but it's Rx. Don't keep it elevated too much. You want the blood flow.

[RKDinOKC]

I'm thinking brake cleaner used to spiffy up the engine bay got on the O2. And while it is not completely dead, it is not putting out the right values.

[vas930]

Hmmm.
Ok, mate.
I would still check it with the old one if you can.
Sorry for your drama.
This type of thing is a real test.

Good advice, Dave.

Good thinking.

[RKDinOKC]

less thickness of skin came off than other blisters I've gotten, the hair is all still there and not curleyed.
