>>>>>> MarkD Performance Chips!

[e30lyf]

I just sent out about 15 refunds today. If you ordered before Nov 28, you should have it now. I plan to send out the remainder after 8:00 pm EST.

Mark

thanks for the quick refund :up:

[z31maniac]

Got my refund over the weekend and used it to buy some 19lb injectors.

Thanks Taylor.

no problemo

1) Its entirely up to you. I dont believe there are any performance gains from upgrading the injector size. Though I run 19lb injectors and I really like it.

Well, there *shouldn't* be, because the only way that would make sense is if the stock injectors had a long enough duty cycle to screw up injection timing and I wouldn't believe that BMW would be so incompetent. Yet, EVERYONE agrees that there are gains to be had, even in fuel economy. Mark suggested 17.5s. Now I need to find a set, I guess: does anyone have one?

2) Hasn't been proven yet but there are plenty of neigh sayers out there that claim it does nothing. I run an M30 AFM, and honestly it just makes more noise under WOT. In about two weeks I will have solid data proving whether or not it actually does increase horse power.

DCC and others suggested it will never work well. Therefore, I'll skip it.

3) My buddy has an S52 in his E30 and he felt a difference but it was only a seat-of-the-pants difference. It could have been a placebo effect in action. I'd say if you have the 3.5" HFM throw it on there and see how you like it. You can always go back to the standard MAF sensor.

The problem is, I'd need an adapter - and that's fine - and a new cone filter - and that is more annoying.
I think I'll focus on building a heatshield to avoid sucking in engine-bay-temp air instead: the flow problems in an S50-in-E30 are elsewhere, from what I can tell and you just confirmed.

Hope that helped
Taylor

It did! Thanks. Back on topic, I'll add myself to the master list for two chips.

If you change to a 3.5" HFM on an S52, you need software that takes that into consideration.

You don't need to add your name to the list as the earlybird part of the sale is over, everyone who orders on Dec 2 or later (till the end of the sale) gets 17% off.

I realise that, yes - I think I'll just skip it for now. Honestly, I am not that interested into putting more time and money into that car for now. Regular AFM it is.
As to the list, understood. I'll take the 17% :).

Hey Mark,

I've ordered before Nov 28th and I haven't got any refund yet nor the chip.

You sent me UPS tracking number through paypal and it says it is not availble. Please check your PM and email and let me know.

Thanks

Alex,

let me check into it. I'll get back to you by email. I don't use UPS. I only sent an email saying "in process".

[desertvert]

It already looks faster.

Helpful too, for anyone who hasn't been inside the ecu before.

[accident]

I've only ever opened ETA ECUs and they all had two boards.

Mark: would you be able to cut a chip for an eta with the 731 head? take advantage of a higher redline? let me know

[E30_fiend]

Hey mark, got my chip yesterday and installed it within 15 minutes after pulling it out of the mailbox lol. I haven had a chance to really open it up all the way so I'll do that tonight when I'm off work. So far I noticed a considerable amount of bottom end in 1st and 2nd and I pull way fuckin hard in 3rd and 4th. So we will see today how it does from a stop. So far though I'm really happy with it. So thanks. I still need to give it some time to adapt because the idle is surging a bit.


Thanks a lot Mark. Big thumbs up.

I can't make any big mods to the chip as I don't want to custom tune for those mods without tuning the AFR etc on a running motor. I can raise the limiter in my standard eta chip if you want.

I did make a chip for the eta block and 885 head, but hardly anyone has that setup.
