Mr Michael B

Forum members!

I recently performed a computer chip upgrade. In grand fashion I also took the opportunity to test the product thoroughly. Check it out!

"up on the dyno again"

Here below are the stats that I know you will all want on record.

The base test has been completed on my personal 1995 3.6 liter six speed DX coupe. Engine was as per factory spec, with the addition of RSR mufflers from forum member Robin Sun. The air box cover is drilled, with a factory type paper filter. 18 inch 265/35 rear & 225/40 Continental tires are fitted for this test.

Next I ran a base line dyno run in the above configuration on a Dyno Jet machine. Additionally I performed several 0-60 & 1/4 mile runs with a G-tech unit so that I could get repeatable acceleration performance figures. The runs were made conservatively, without abuse. The test vehicle was shifted at redline in each gear, and completely dressed with street equipment.

The figures were as follows:

"Stock" configuration 0-60 = 5.3 seconds
"Stock" configuration 1/4 mile = 13.79 @ 107.9 MPH

Now, for the tasty bits. Here are the figures for after the chip upgrade:

"Chipped" configuration 0-60 = 5.2 seconds
"Chipped" configuration 1/4 mile = 13.62 @ 108.6 MPH

The chassis dyno showed a gain of 14 horsepower & 15 ft.lb of torque at the rear wheels.

Additionally the car has improved drivability around town. Zipping around traffic has never been easier. Useable power in each gear is improved substantially throughout the RPM band. The full 993 experience is vastly improved with no downside. Lastly, install is simple, and can be completed with ordinary hand tools.

It is truly a win-win.

What is the entry fee you may ask? How about $375 for the 1995 removable chip version & $975 for the ECU reprogramming for a VarioRam version.

Who produces this fine product? It is a GIAC production brought to you by ImagineAuto through EVO Motorsports. It is the exact same chip that we forum members have all have known & admired all along, just at reduced pricing.

It is the next level of ImagineAuto chip tuning, now for the 993 model Porsche.

I hope with this exhaustive testing that you will consider a ImagineAuto.com chip for your machine in the future. I am glad I did!

Sounds like you've been busy, spending lots of time staring at computer screens and such.

thanks for the info.

Interesting improvements. Do they have a chip for the post 95 cars?

Also, do you think this would be a first priority in engine upgrades?

thanks in advance

(PS if that dyno is in your new garage, I'm telling your wife.)

Is there any additional cost for us '96ers who have the nonprogrammable chip?

Mr Michael B

Mike!

Ha, geezz. The wife is going to kill me... Oh & yes, all 993's & chippable 911's are covered (even watercooled Porsches!). Just different price for VarioRam or NonVarioRam or 3.2 Carrera etc.

I do indeed think that the chip is a fine "1st upgrade." Nothing else is needed, plug in & go.

ESL (great avatar),

The 1996 is a strange breed. We talked about it with them. I know it can be done, the 1997 ECU works fine with it. Expect the same gains too.

Eric in Chicago

Great MB,
That is all you need, more HP. Now I will never catch you... Ruther asked me to instruct this year so we can have some fun in the fast group!!

J-McDonald

Thanks Mike - do you have any dyno charts with before and after hp and torque? I'd be interested to see how the gains are distributed across the rpm band.

Jack Ennuste

Michael

What is the cost of 1 improved hp using re-chipping, like You did? Would You be so nice and calculate it for us?

chris walrod

Michael, great work! I would like to graphs as well. Especially the torque curve stock vs.chipped. What octane was this test done with?

Looks good!

Chris

Mr Michael B

Sure thing guys. I have the chart. Please keep in mind that the power is gained in the heart of the rev range (nicely gained). Peak power remains safely tuned at factory specs. If you just have to have more peak power we can pull out some of the fuel towards the top of the rev range. It feels quite nice as is though & is very engine safe.

Jack man! Your hilarious <img border="0" title="" alt="[Wink]" src="wink.gif" /> $25 bux per HP w/ chip. What's yours? $75 per HP? Gotta luv that.

You know... I may be testing an intercooled supercharger this next season... Better watch out! I will try to get it down to $50 per HP on that unit!

Here is the graph:

Mr Michael B

Here is the torque chart:

<img src="http://boards.rennlist.com/upload/993dynotorquestockandchip1995small.jpg" alt=" - " />

I took the liberty of having the program show the actual TQ difference in the meat of the power band.

15 ft. lb gain for most of the rev range.

Not bad for $375 'eh.

Terry Adams

A nice gain, even for the $975 it would cost me. As Greg said, you can have it cheap, fast, and reliable. Choose two....
Does the higher air/fuel ratio lead to hotter running engine, hotter enough to affect long term reliability?
I ask because the difference in A/F ratio at 4K rpm is much greater in the HP graph than in the TQ graph. Maybe I am not reading it right.

johnfm

I take there is 'no affiliation', just a 'satisfied customer' etc etc??

Mr Michael B

Terry,

You have a great eye.

That # 5 run (with the leaner fuel) was after a "hard boot" of the system (meaning battery unplug and re-drive). I was looking to see if the chip would "reset" afterwards. It did, and was compensating for the "new fresh start."

The car in even stock form runs pretty rich, it can stand to loose a bit of fuel, so reliability will still be a strong suit. Its still plenty fat, and very safe. Great question.

Johnfm,

I am as affiliated as they come! <img border="0" title="" alt="[Wink]" src="wink.gif" /> This is the kinda thing I do for the forums!

I had a tank plumb full of "BP 93" (Amoco). The chip is set for 91 octane.

Thanks again for the avatar! Do you know if I'd have to buy a '97 then have it programmed or could I just swap the '96 for the '97?
