This Saturday at Walker Dyno in Trussville, info on the albmwcca.org under event registration. Still several slots available, register even if you are hanging out, they may have food.
Let me know if anyone is going, I may hang out and meet people for a couple beers.

Robert,
What time are you thinking of going?
Blake Walker said that only 5 officially sign up for a slot with Steve Lowery but that other people may be hanging around to do it later. They were going to start at 10am.
I never had my car dyno before and very curious to see it's capability in terms of raw numbers.
I was thinking about mosing over there around noonish after the 5 cars get their run out of the way.
Later,
Monchai

Actually my wife informed me that I am occupied all day with a girl scout function for my daughter at lunch time and then going with them to the Disney on ice thing. I won't be able to come up.
I recommend going by for a cheap dyno, get 2 or 3 runs to see what kind of power you are making, $45 is pretty cheap for 1/2 hour on the dyno. It'll also give an indication if you have any problems with the motor such as detonation due to poor injectors or something along those lines.
Put some 93 octane in the car and take up to there, Walker is a kikass guy. I just put a new AA exhaust on the car but I will wait to dyno it after I throw the M50 intake manifold, software, and 3 1/2" hfm on the car.

93 octane? :confused where do i get that at? I think I can only get 91octane (Premium) at Chevron (my usual spot since my gas card..lol).
Nat said to put some octane boosters in it if I cant find 93 octane.
Yeah I'm curious to see what my power mods will give me:
3.5 HFM, UUC pulleys, stock 17#injectors (boo) :( , OBDII headers (boo) :( , Supersprint resonator and B&B Tri Flo exhaust.
Next upgrade would be some cams, bigger injectors and real headers..hopefully Santa will be nice to me..lol :D

Pretty much everyone around us has 93 octane as the premium gas. I go to the Chevron on 150 just after passing under 459 headed towards Bessemer. If you are buying premium you are likely buying 93.
Your car should put down some strong numbers with that set-up. When/if I upgrade to 24# injectors soon I'll sell you my 21.5# injectors pretty cheap if you want them.
Who's software/chip do you have to use the 3 1/2" hfm?

Ok, I guess i maybe retarded with the octane number. I could have sworn (last time I paid attention to the octane rating..God knows how long that was) it was 91 for premium since 87 is regular and 89 is mid grade and 91 is octane.
But if it's 93 for premium then that's good news for me !!!

I'm using a Turnermotorsport chip for my stock 17#injectors with the Euro HFM setup. I probably need a new chip since it's not "tuned" for the current upgrades (exhaust, resonator, flywheel, etc)
But I'm kinda waiting to add the final ingredients first before I get the chip tuned for all the mods.

There's a guy that's about to sell his 24 and 30 lb injectors online later today.

Also, another guy is selling his LEVEL 4 AA's setup along with AA's track pipe on Ebay (8011904926).

I was on my back nursing a thrown shoulder - it's much better now thank you very much -

Even if I could have gone - I'd have wanted to Dyno the M6 - which has no front seats at the moment cause I'm getting them re-done at Vines -

I still may go dyno it at regular price (like 65) before i sell it just to see what it throw down and to give it sort of a "pedigree" before selling..

Then - I think I'm gonna dyno the E39 528 to see what the baseline is before i start modding it.. find out what the chips/CAI's etc really do - in the "real world" setting.

Defintely after I get the APEXi ARC II, I'll get Blake or someone from Integrity to wire it up. Then Blake will tune it for me since he's the only one in town that knows how to play with that thing for BMWs. His wife's 99 M3 puts down 243hp to the wheels with just custom Air Mass meter, CAI, Pulleys.

I'm going this route instead of getting a static burn once chip since you are at the mercy of the person who programmed it. I think it makes more sense to tune the car (using the AFC ARC II) on the fly instead. Plus, I can't afford to get new chips burn everytime I add or change something.

Thoughts or comments on my logic?

See you guys later at the next Dixie Chapter Event...

Who is this Blake PErson you speak of? I didn't know there was anyone locally that could re-program our cars/chips, etc.

I agree with the logic - it's better to have a chip/software tuned specifically to your set of mods - much better off there-

The guy you are talking about had a red turbo M3 that was wrecked a while back, he does really good welding work out of the performance shop in Pelham (SpeedSouth). Last time I went by there he was welding up beautiful piping to turbo charge a Yamaha Z-Max, insane.
H made a custom 3 1/2" tube and put the guts from his 3 " hfm into it and tuned the air/fuel signal with the Apexi. With exhaust, custom intake, 24# injectors, and the Apexi piece he made almost 250rwhp. The guy that runs the dyno showed me the chart with like 15 runs on it where they did a run, made some tuning, did a run, etc.

I believe his name is Blake Walker, the "owner" of the Walker Dyno Shop in Trussville.

He told me that in his wife's E36 M3 has a APEXi AFC II Controller (piggyback Air Fuel Calibrator system that taps into ECU wiring harness..
http://www.apexi-usa.com/product_electronics.asp) that he knows how to adjust fuel mapping, timing, etc etc (all beyond my simple comprehesion) to get the max HP. I'm not sure if this method is the same as what Jim Conforti does to the chips. I'm guessing it is very similar except, with the APEXi, you can tune on the fly on the dyno. He said to go to Integrity (a shop in Trussville 655-6310) to buy and have the APEXi AFC II installed.
Then he said to come back to his dyno shop and he'll have it the car tuned up for max HP. He said that he can tune that APEXi blind folded...lol

Retail price on the APEXi AFC Select or AFC II is around $399. I plan on price shopping online and have the tech (Andy @ Integrity) install it. Andy says that it will ~2hrs of labor (@$50/hr) to tap into the ECU wiring harness..yada yada.

I think it's worth the money. Especially, If you can get the APEXI for around $150.

Anyways..that's about it. I'm waiting for the auction to end to see if I win it..lol

I'll keep everyone updated.

Yeah, the guy that did all this first and figured out how to do it was named Walker, he's a poster on these boards a while back. Blake owns the dyno shop and knows how to do it now, sorry I got confused.
I had the Apexi AVC-r boost set-up in my 95 M3 turbo and it was awesome, they make great electronics for car tuning.
Here is my take on it, I was going to do this set-up on my last M3 and never got around to it, they told me last summer you have to do the 24# Ford SVO injectors with the Apexi piece and I'm not an expert but...
The piece Blake uses takes the signal from the hfm and makes adjustments to it and sends the "trick" signal to the ECU to dump more fuel in the motor at certain revs based on airflow, this is normally achieved by software people like AA or conforti as well but it still uses the adaptability built into the ECU. Several guys over the years have tried making this set-up work on a vanos BMW but this seems to have been the most successful. The only bad part of it is that you have to constantly be adjusting based on elevation, humidity, temerature, etc. whereas if you have software in the form of a chip or downloaded software it will adapt to those conditions just as the factory ECU will but with more aggressive timing and fuel charts.
Tuning with the Apexi will be static, you tune it for optimal on that day on that dyno but the next day if its dryer and 5 degrees warmer the dyno chart could be substantially different. Instead of the Apexi piece saying "dump this more fuel in at this 200rpm rev range" the software from Conforti or AA would say "dump 5% more fuel in at this 200rpm rev range whenever the air volume is XXX."

damn- - if I still lived in Birmingham I would make it out to this event. Next time...

Robert,
So with the above info, now I'm having second thoughts about getting the Apexi AFC controller. So what you are saying, is the AA or Conforti chip have a built in algorithm/rules that will compensate for all the different variables?
The Apexi is only good on the day that it was optimally tuned with the set values. So like u said, if things change (humidity, temp) then you're "stuck" with those set values.
Well, I guess I was under the impression that I could always adjust the Apexi on the fly..but I'm not well verse to understand all the different variables.

What would you get? Chip or Apexi Controller?

Thanks,
Monchai

I am not sure if my thought on how tuning the fuel delivery with the Apexi works but since all it really does is trick the air flow signal to the ECU to delivery more or less fuel at any range than I'm guessing thats right. It may be fine but I don't know 100%.
I think I am going to do the AA stuff on my car, Karl Hugh and I exchanged e-mail about software and he said he has a nice download available for a 3 1/2" hfm and M50 intake manifold, so its like doing the best parts of an OBDI conversion but without breaking federal emmisions laws. I will see close to the same power levels with those mods on my car than someone would see with similar mods and bigger injectors tuning with an Apexi fuel controller.
You may be fine with your original plan, I really don't know 100%.

Is this exclusive to BMWCCA members or can anybody with a roundel sign up?

It is supposed to have been for BMWCCA members but nobody was checking cards at events.
Plus, this happened over a week ago.
