dyno'd the 2.7i

[ForcedFirebird]

Good luck, most tuners don;t really mess with Motronic, might end up having to go to a Porsche place since the equipment is similar. Dyno tuners generally charge about $300 around here, specially seeing the dyno itself is about $150/hr. The guys like me at the place we take our cars, they will charge us $75 for 3 pulls and this last time they let us change the tune 4x, and we realized the inj were going static, otherwise they would have let at least one more lol. Been going there since they were one bay with a dyno in another bay, now they are up to 4 (really deep) bays and TONS of AWD cars going through there.

Right. A tune made for your car at your altitude with your mods etc is going to trump a "generalized" chip.



I still have the e cluster, I know when I am about to hit the limiter when the needle starts bouncing all over the place haha.

I swapped out the entire harness to the Motronic 1.3, it's really not tough. The most difficult part for the "non-mechanic" woudl be grinding the passage through the firewall to allow the larger ECU connector and wiring in the tach/econoguage in the glovebox, but it's only 2 wires.

Cool man, i think i'll look around for a place that can get me a tune.

and yeah, it's a pretty straight forward convertion. don't let the really simple electrical scare you. its easy enough to the point where, if it is over your head, you just come out of the project a little smarter

[ForcedFirebird]

so is it just as simple as
custom tune>stroker ship>no tune?

So I have a question on your 2.7i. Do you still use a eta harness and cluster? I'm considering doing this if there isn't a lot of wiring involved.

There is, but to me they seem the same as the i tune (aka strokers with pistons similar to the i). MY car likes something totally different than I have seen from any .bin file that's circulating or read from the major chip suppliers.

EDIT: They are probably selling tunes that will work with a multitude of combinations. I am tuning my car for what it has (same with our local street tunes). You can't really sell fine tuning over the internet with Motronic, but you can sell an enhanced stock tune.

i guess i'm a little confused. i thought there was a chip available for e to i strokers....

i want to run an 885 head... how do inquire about the markD chip?

[Stephen]

There was the e to i hybrid chip for guys running double valve springs and i cam, bumping the r3v limit on motronic 1.0, as i recall

[accident]

MarkD made one, he just doesnt advertise it.

Just about ready to go back! Got the tune going good, can't believe how lean the car was, nor the fact that the timing was wayyyyy off. Car pulls even stronger than ever now,and the timing was bumped from the stock by a long shot. Doubled in some places 0.o.

We also tuned a stock 2.5, as well as a 272 cammed 2.5 and the 2.7i likes something totally different. I have a feeling that many people running the 885 head on a stock ETA bottom, even if chipped, could be making more power if the chip in use, was designed for a actual "blueprinted" stroker and not stock BMW parts miss-matched together. So far I have done street tests on some other major chip sellers and they don't work that great in my car compared to my street tune.

The 272 car after a street tune, the owner told us that it felt the same as his internet-purchased chip, only ours idled better and felt a little smoother.

now the dyno makes more sense lol

[ForcedFirebird]

on the rollers


pic of their shop (they have an 8sec EVO)


new injector harness


new injectors


Felt so inadequate compared to some cars there, but they like us haha

[ForcedFirebird]

Here's the 2.7i with stock inj running 65psi through them, stock tune...



and stock inj with 3bar (43.5psi) tuned...



Can you guess where the injectors ran out? haha!

EDIT: don't try and decipher between the two, we had them change the scale mowahaha.

[ForcedFirebird]

Stock injectors went static today at stock pressure, big surprise ROFL!

Last trip had stock inj at 65psi/stock tune...
