I don't know if you have heard of a guy that goes by"Turbo Mike", from Hacienda Heights, CA.

He has installed several of my controllers, used in conjunction with a F.A.S.T. EFI.

Here is his car on the dyno with my system:

The MSD knock alert is all analog. Not that there's anything wrong with that, but it doesn't even have a knock window, which is a form of noise blanking.

No one heard of Turbo Mike? I think he's Armenian, or has some accent like that.

Nope, never heard of him.....

Found a little more public information on him from GT Pro's site

John, you seem a nice guy and you have a nice product there. You seem to have developed it well and it is very up to date.

The problem is, with the 930 the timing chain ramps are very noisy and this is why your product is not as suitable for us as it is for other Porsche air cooled engines.
We're a very small market so it's not much of a loss to you.

Hi,
I'd love to have one as I'm sure we all would. The people with 930's that I have heard that have had them deployed, pulled them back off. I tried to get my ECU salesman to sell me one and he wouldn't.

I don't know Porsches. How similar are the cam chains on a 911?

The 911 was our first test car in a magazine, must have been early '91. I rode along with an oscilloscope on my lap, since I had heard stories about how noisy these engines were. Not true at all. I was surprised at how quiet the engine was.

The owner was an engineer at CalComp, who had reverse engineered the Motronic chip. He had a version he used on the weekends with more timing and less fuel, and that's what we ran when we tested the unit. Can't remember his name, maybe I can get hold of James Sly. He probably knows. I think the guy that installed it was Greg Brown, a Porsche mechanic here in Orange County.

Nice thread. Porsche tuning community has largely made do with no form of knock control because SO FAR nobody has come forward with the right product. ALL knock sensing systems register false occasionally but what a good system can do is help you tune the car beyond what`s possible sans knock control. The DSM tuning community is well familiar with the bane of pulled timing from false positives on their knock sensors but the mega high power turbo motors need the knock control systems to attain those high power levels.Some early Fuel injection systems were pretty bad, maybe the time has finally come that someone has developed a system that does more good then harm? l for one am interested in the system and suggest that J&S get some units out for testing. l`ll take one at a good price and real world test it and pass it on to the next guy,etc. lets get this on :)

If these work, they'll sell like Hot Cakes, no doubt.

Kinda related but figured some yous might get a goof out of this one...

A bud of mine does alot of chip tuning in the Audi circles, been working closely with VEMS lately, etc.

He just rig'd up this neat little concoction as he too is skeptical of knock sensors and 'normal' engine 'noise'. He wired up an adapter harness to a factory audi knock sensor to a standard microphone jack. Plugged that into a laptop PC with a set of race style headphones plugged into the headphone jack.

Which allowed him to produce this on a stroker '95 //S6 pushing around 400allwhp:

Pretty neat. He's a madman, gotta love it.

Interesting... Keep in mind that that has a crankcase and head come with water dampeners in it to quiet it down a ton. I think that it would not be hard to detect knock in that engine. There ain't no way a 930 engine sounds that tight with a microphone.

Oh I know (good points), but the timing on this thread and my bud doing that were uncanny so I thought I'd share as I found it kinda cool.

it sounded cool...

I didn't hear any knock....

Any of the SoCal guys know Rick Hearn? I had forgotten his name until I spoke with Greg Brown of Precision Motorworks in Anaheim today. He remembered doing the install of our system on Rick's 911 back in '91. This was our first magazine test, can't remember the issue.

Rick was an engineer at Calcomp and had reverse engineered the Motronic chip. He programmed one with more spark and less fuel and ran it when he went racing on the weekends.

If the unit was retarding inappropriately, it would have shown up in poor or inconsistent lap times.

James Sly was a technical writer for European Car at the time, and he told me Greg went through the engine three years later. Greg told him (paraphrasing) without the knock controller, there was no way the engine would have looked that good running Rick's chip.

John (J&S),
It sounds like you have a product that is "useable" and I commend your hanging in there with this post. Assuming someone was to install your system on a 3.2 911 engine, (non turbo 1984 through 1989) , where would you suggest the sensor be located or do you recall any customers who noted this?

I think Ivalt's installation used a single sensor. You might ask him if he's still using it and where it's mounted.

He posted in early April that he was going to the dyno, no forum activity since. As they say, no news is good news.

Turbo Mike used two sensors in his installations. I've been on a couple test rides with him, but never looked at where he mounted the sensors. He can be reached at innovativeprodesign.

First unit is up and running. I spent the last week "porting the code" to work on the new processor.

Ray Sedman at american-pi.com will be showing it next week at the Corvair convention in Ventura.

http://conventions.corvair.org/2008/

Over the years he has sold maybe a hundred of our earlier systems to his Corvair customers.

I posted pics last week in this thread:

neat stuff. l would really like to get one of these once you get the system dialed in for our cars.l have a 1984 3.2 Carrera with a turbo system, l`m running conservative boost and have a huge intercooler..
