Mark D 93 M42 Octane Chip

[bavarian3]

Hello all. I hope this forum has great success!

I had three M42 guys e-mail me requesting about a true 93 octane chip for their cars. I just wanted to let you guys know that we are able to get a true (not a tuned 91 octane that *could* run 93) 93 octane chip.

If you are interested in a custom M42 chip, please let us know.

Thanks for looking!

[m42 fan]

Tempting, but since I might get relocated to California someday, I'll stick with my 91 octane Jim C. chip for now.

[fabby318is]

Please tell us more, such as the differences between the new chip and the old one.

Also, is it a strict 93 octane chip or can it run ok on 92?

Thanks :)

If we can get a group buy discount, I might be interested.

ditto, i only ever fill up with sunoco 94 anyway

[M42boy]

Some parts of the country, 93 octane is hard to come by. In Washington State, we with turbo cars used to make special trips to the Cenex which was the only station that sold 94 octane pump gas in the city.

I had a GP on R3Vlimited but if I can get 10 M42 guys, I can do another GP.

[zerofreez]

It wont happen... i posted the group buy from r3v on here and got no response.

[bavarian3]

You have to give it time... I understand that a lot of members are not always on the same page or want to spend at the same time....

In any case, if you guys need a chip, please e-mail us!

Our price on the chip is $219.

I am interested in the chip as well but I would like to know some more details. What gains can we expect to see with this chip, any dyno sheets to show?

MS is not as cheap as a chip. Not many people would be able to competently tune it either.

For a stockish motor a chip is the best way to go.

Yeah I'm in south dakota and they only sell 92 here,, anyone interested in a GB for the 91 octane chip?

[rabidroco]

I want one, how do i get it?

Haha! The MS was an ordeal when I did it a few years ago. Definitely cost as much as like 3 chips by the time I bought all the tools, electronic diagnostic equipment and WBO2 setup. It was a good experience though...too bad the car got crunched!

I WISH I had 93 in CA. I would be all over that chip...for now though the Jim C one will have to suffice. Comparing the 91 chip you sell to the Jim C one...are there any differences in performance?

i'm interested in getting a Mark D 93 Octane chip as well. I recall last year their was a Christmas time sale and I saw Mark post a few months ago that he would likely repeat the sale this year. Any word on that?

I got in on the Abrahams MS GB on this chip....it's VERY well done IMHO

I have always used Jim C chips (I have one in my e30M3, and had one for the m20 motor as well) but I gotta tell ya, the butt dyno really reacted well to this chip. It's alota fun for alittle money.

cheers

I'm glad you like the 93 octane version. Chip sales are rather slow this time of year so I usually run a winter sale. Right now, you can get 8% off on any chip available on my website. Just order it and in the PayPal comments field, mention promo code M42WS. I'll send you an 8% refund within 7 days of ordering. Chips are usually mailed out each Monday by USPS Priority Post.

If I get 5 orders with that promo code by Feb 18, I'll make the discount 11% off on each chip.

Does anyone have any dyno's and/or A/F graph of this chip on the m42?

Any noticable differences between the 91 and 93 versions?

[silverblades181]

I'd like to know the difference between the 91 and 93 chip aswell.

[bavarian3]

I believe Mark adjusted the timing to be a bit more aggressive with 93 octane.... As far as how much adjustment is in either, I cannot answer.

[EducatedFool]

i would also love to know the power difference between the 2 chips.
