Well, the time has finally come...I had to wait all summer for my tuning session with Dave at KDR, but this Friday is the big day. He'll be installing/tuning my PFC, and I'm just wondering if anyone who has been there has any suggestions. He's already reassured me that if I do have the A/C problem upon installing the PFC that he'll correct it, and said that he doesn't foresee any big problems.

Anyway, is there anything anyone would recommend bringing with me, or anything I should ask Dave while I'm down there? I'm really looking forward to hanging out in the shop and watching him do his thing.

 

New spark plugs

 

Yep. Just make sure everything is in good working order before you get there. If you have time, maybe run a can of good injector cleaner thru your gas tank. BG44K is good stuff.

 

Thanks guys. These plugs have about 1k miles on them...Should I still change them?

 

I'm sure the guy knows what he's doing, so you should talk directly to him. He probably gets the question all the time, especially if he makes a living doing this!

Make sure the motor is, in general, working properly (no oil pressure/water temp/fuel pressure-injection/spark/compression/starting issues, etc.)--otherwise, your car will have to be fixed first. Also, remind the guy exactly what you have done to your car (has Dave done all of the work or someone else?) so he can anticipate how to handle it when he's tuning. Is he doing a power tune or just basic tuning for idle/cruise or both of those and everything in between? Remember it takes time to tune all of the other stuff "in between".

Lastly, bring some patience and a willingness to learn A lot of people don't realize how time consuming and complex tuning can be... don't forget that your car is going to be tuned to certain conditions and that when you get the car back you have to be very concsious of the operating environment when you push it.

If you want to learn more about what tuning the PFC is all about, get Chuck Westbrook's notes. PM cewrx7r1 and ask him for a set. He sells them and provides updates from time to time. Probably the best money spent on your setup, considering you made the jump to the PFC. Even though you're not tuning the car yourself, you can hold an intelligent conversation with the tuner and learn something in the process.

Good luck

 

I would put new plugs in just before you start tuning.

 

I would, but anyone who has worked with Dave before knows he's extremely hard to get ahold of. I shot him an email this afternoon, so maybe he'll write back before Friday.

Again, thanks for the advice guys. I'll put in fresh plugs and run some fuel injector cleaner through before the tune.

 

Was just down to the parts store and they don't have any BG44k...Is Chevron Techron ok to run through? That's what they recommended, but I never trust them without getting a second opinion...

 

Anything is better than nothing. BG44K is hard to find. I would get some to use at a later date. For BG44K, pour the entire bottle into a full tank of gas. Do not use it more than once a year.

 

So your the reason why I could'nt get tuned Friday!...LOL
fill up with 93 octane, as I was instructed.

 

Yep, that's me! :P
Anyway, filling up with 93 shouldn't be a problem, since that's all I ever put in it.

Btw, when's your tuning session?

 

I would also change the fuel filter...How many miles on the filter.

BTW, for the first timer, changing the fuel filter is a PITA!

 

Fuel filter has less than 2k miles on it. I changed it when I first got the car. Having a lift helped, but it was still a huge PITA!

 

Welp, went to see Dave and things went pretty well. Car hit 330 RWHP on the last run, with the torque at 286 lb/ft.

Unfortunately, as I suspected previously, I have a coolant seal that's starting to leak. However, the motor didn't pop after 8 hard dyno runs, so I'm just keeping an eye on everything to make sure she doesn't overheat. At the moment I only add a small amount of coolant to the filler neck once every week or so. Dave mentioned he's known a few people that've driven around for years with seals that are leaking minorly.

 

Glad everything went well! Is that your full mod list in your sig?

 

Thanks! And yep, I've updated everything in my sig, so those are all my current mods.

Here is the dyno sheet of my best run...He labeled it "14 psi," but it would only creep to 14 around 7400 rpms. Most of the run the boost was sitting right around 12 psi.

 

Nice powerband Do you know what the intake air temps were for your runs--in particular the one that you show in the pic? Just want to see what kind of variation in power you had as the air temps changed.

 

Nice #'s

 

IIRC, IATs were right around 40 degrees Celsius during that run, but I don't remember exactly.

 

nice #'s enjoy

 

Sounds like the Ebay IC works pretty well. Do you have it ducted?

 

Gives me hope for my car wanted to make over 300 lol

 

Yep. I just took the old ducting, cut out where the shroud was that went around the A/C, then removed the rivets. I also used a piece of old ventaridge to block the hot air rising from the radiator fans, but the air can still escape to the sides. Keeps the IC MUCH cooler.
