MarkD M42 chip - what happened?

[MarkD]

sorry if this is too off topic but I didn't think it warranted a new thread, I was just curious what happened to the 93 octane m42 chip. I thought Mark was making m42 chips for 91 and 93 octane and some people argued for the 92, and now there is only 92? will there be a 93 octane m42 chip in the future? thanks

What happened is that I had made the chips without actually having a car to develop them with. I made the changes to timing and fuel theoretically. I was quite conservative in the timing for that reason. It turns out that one person is even using the chip I made for 93 octane in CA, with 91 octane. So all I plan to ship for now is the chip originally labelled "93" which will be the new 91 octane version. I'll make a 93 octane version later if there is any demand. And I'll tune it on the dyno, now that it is properly working (if I find a car here in Toronto)

i can run 94 where im at i want 94 hahaha, im interested in the chip but i ogtta get my rims and suspension here first. This should be by the end of this week beginning of next so then ill be up for it. You know how it goes i gota get my tires paid for first. Id also like to know performance gains for my m42.

I'll run a group buy on the 91 318iS chip if anyone is interested. I need 6 orders minimum, the price would be retail - 10%

Alright I'll see what I can do with the Group Buy....

My roomy and I (both with 318is) are going to get in on it. I see it organized on bf.c, still looking for a specific thread for the CURRENT GB on here.

Mark, I'm also looking for the gains to 'sell' the chip to my roomy. I don't see any specs (other than the raised rev limit) on your site. Can you tell me any more about it? Thanks!

Oh, and you mentioned the person in CA running it with the icky 91 gas we get here. I would guess that means he isn't having pinging problems, correct? It would suck for us if he HAS the problems and just is ignoring them...

-Bump-

Mark D's website shows only a 91 Octane chip. I have read elsewhere on this forum that there was a 93 Octane M42 chip.

Are 93 Octane M42 chips no longer offered? What's the deal?

[Bavarian3]

Aj,

Mark makes the 93; but hasn't listed them on the site. You can either contact him or Mel (mel@abrahamsmotorsport.com) regarding the 93 octane chip. I ran a small GP for Mark awhile ago and sold three 93 versions.

Hi,

Thanks for the reply - I e-mailed w/ Mel an hour or two ago, and he said Mark doesn't produce 93 Octane M42 chips anymore, stating that there was no power gain over 91 Octane chips.

I don't know who's right or wrong - just looking for some details.

Thanks!

I'll try to get hold of Mark and get an answer this weekend.

Just heard back-there is only a 91 octane chip available for the 318is.

I finally drove a MarkD chipped M42 before and after last weekend. It's a really noticeable difference, especially in throttle response and mid-range torque. I was skeptical because the M42 makes pretty damn good power for its displacement (for a motor design 17 years old anyway), but the chip really is a nice addition. On par with the M20 chip, I'd say.
