Best choice of chip?

[zandi]

Go with MarkD, he makes chips for 380s and i think his 173 works on the 380

[Digitalwave]

i already have 4.10.


i ordered markD 380 91oct chip

He should make 93 octane ones man...

he has 93 oct, but i dont know if he has it for the 380 DME yet.

no gas stations around me have 93 oct though :(

Negatory Ghost Rider.

All the gas stations in our area have 83, 85/87, and 93 octane. we have no 91 here in SE Houston. .... from what I have seen.

83? I've never ever heard of anything that low. We have 87, 89, and 93.

us canucks got 87, 89, 91

Yes, I have heard this may be the case. I have not heard for sure from him on this though. It sound like from his last post above,

I do have it, just have not updated my site yet!

I'm off to a 3 day driving school . . .

MarkD

that the 380 chip may be done. Still waiting to hear though.

Here in Louisiana we have 87, 89, 91........ :?

[PanamaE30]

We've got 91 and 95...

Although I'll bet you a million dollars it's really 89 and 93 :P

i got the 93 Mark D chip for my 380 DME, i think he actually sent me the 173 but obviously having no care for my car i tried it anyways and it works great, just above 3k rpm theres an awesome jump in power. just need injectors and AFM upgrades to complete.

BTW, i origionally thought that we only had 91 octane here in houston, but we do infact have 93 as said by others.

Heh, did you really think the entire country (which of course remember is larger than the USA) has the same octane ratings coast to coast?

We get 94 here, and my car sees no less (MarkD's 93+ chip was developed in my car).

yah i found this out too... half the gas stations around me have 91, the other have 93

I contacted Mark about the e30 chips to get the word on using the 173 chip in a 380. Here is what he said:

The 380 chip is just the 173 chip with some more diagnostics. You can actually run the 173 if you don't care about a few extra DTC's (diagnostic trouble codes)

But I'll make the chip very soon, for those who care about the codes.

Thanks

Mark

Great guy, busy as always. I think I am going to go ahead and use the 173 chip for now and maybe get the 380 down the road. It would be nice to think that I wouldn't NEED the diagnostic codes! ;)

Just ordered my chip, gonna go park my car out by the mailbox and wait for it! 8)

Can someone recommend where to go to find a 4.10 LSD for my '88 325is, and how much I should pay?

Also, if and when I install it, is there a market for my low mileage (125,000) 3.73 LSD?

[KeeperJones]

WOW, nice! The 93 octane MarkD chip is in, and life is good! 8)

Oh, and the 380 ECU install is a breeze. There is only one board and all you have to do is pull the cover to get at it. It took me maybe a half hour to change it out. The other difference is there are four small screws in the top of the cover to take off. Easy install, and I am sure probably the best performance/cost ratio mod.

I am currently running 92 octane and it seems to be working well. I had arranged for some 100 octane fuel to mix up the 92 to 93, but I don't think I am going to need it. I am going to test it out the next couple days and see what happens.

Another very satisfied MarkD chip owner. Way to go Mark :!:

wow... it took me like 5 min.

i got the 91 chip, just because some places don't have 93 when i go on road trips.
