Disney, your Gelbart man today: He's got a couple more tools your shop needs.

FWIW, I told the customer I couldn't figure it out. I suspected either a bad ECM or a bad input to the computer that I couldn't identify. He took it to a dealership. Dealership wants to put injectors in it, for $8-10 K !

That didn't answer my question....

For sure heat is hard on electronics. But does a Camaro charge a battery like a Tahoe? They will turn off the alternator for a time, then turn it on. Economy, they say. Monitor the computer for inputs such as Voltage, any battery temperature, actual vs desired voltages, alternator output pulse width. How was the "bad battery" tested? A funny charging system could have cooked it. (15.0 volts in the wintertime is OK, summer...probably too much by about .5 volt.)

A woman in a hot air balloon realizes she is lost. She lowers her altitude and spots a man fishing from a boat below. She shouts to him, "Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am." The man consults his portable GPS and replies, "You're in a hot air balloon, approximately 30 feet above a ground elevation of 2,346 feet above sea level. You are at 31 degrees, 14.97 minutes north latitude and 100 degrees, 49.09 minutes west longitude." She rolls her eyes and says, "You must be a Republican!" "I am," replies the man. "How did you know?" "Well," answers the balloonist, "everything you tell me is technically correct, but I have no idea what to do with your information, and I'm still lost. Frankly, you're not much help to me." The man smiles and responds, "You must be a Democrat." "I am, replies the balloonist. "How did you know?" "Well," says the man, "You don't know where you are or where you're going. You've risen to where you are due to a large quantity of hot air. You made a promise that you have no idea how to keep, and now you expect me to solve your problem. You're in exactly the same position you were in before we met, but, somehow, now it's my fault."

Regarding P219A and P219B: Diagnostic Aids * The fuel trim cylinder balance diagnostic is very sensitive to HO2S design. A non-OE sensor or an incorrect part number my cause a DTc to set. * Certain aftermarket air filters may cause a DTC to set * Certain aftermarket air induction systems or modifications to the air induction system my cause a DTC to set. * Certain aftermarket exhaust system components my cause a DTC to set.

Has any of the factory sealing/ducting around the radiator been "modified"? Make sure the fan pulls all the air through the rad. Have you slowed the water pump with a pulley swap?

I don't recall if he put out a boost number or just had the assumption. I'm thinking he gave me a number for boost PSI on the starting line, I might have assumed he had a reading down track.

Well, that's his theory of why he needs a bigger turbo than the one that already seems too big to you and I. It doesn't make sense.

LOL! That's a pretty low bar!

I think he's got a gauge and quoted what PSI it made, but I can't recall. It seemed to me to be enough boost to indicate it outta be able to move some air once WOT at load, HOWEVER, we both agreed about the way a turbo can "spool" because of pulses of air (stutter box style, retarded timing, ect). So, could a "too large" turbo actually make 10 or more PSI on a stutter box, yet loose that at WOT? Turbonetics sized and sold him the turbo, and it is the smallest they had. The guy is a machinist/racer who can build neat stuff. First time with the turbski though. http://www.omwracing.com/index.htm

OH, tainted nose hairs! The worst! lol

Dang, a manual and an auto go down in one post. I don't know which to insult.... Hey, I'm happy it's shiny side up and you all got to have a round trip.

ATV, 1 cylinder, 1 liter, estimated 120 hp on engine. It's carb'd, and has had a 48mm turbo added to blow through. Man says it builds boost on the starting line, but the engine doesn't make hardly any more HP than before turbo'd. He is fixated on turbo sizing. On one hand it's like a 350 hp turbo and I'd *think* it's too big. On the other, he can build good boost on the rev limiter/stutter box, he thinks turbo could be too small. Can of worms...anybody wanna guess at a solution?
