EAT, Dinan or AC Schnitzer?

[Sweetwater]

Sweet, I understand that there may have been an issue with some 530iA's in the very early development of the M60B30 chip (interaction with the tranny chip) once Mark had finished the 540's, but I believe that has all been worked out. As far as I know, there have never been any problems with either auto or 6-speed 540's. I ran one of Mark's Beta 540i/6 chips (in fact it's still the one I run) and am totally pleased with it!!! I think you would be too, but I will ask him. I'll check with him to see what the situation is on the 530i chips. While I do that, if you were to record the DME number of the controller box, that might help determine if there are any issues with your car.

Cheers,
Duey

Thanks Duey,

I thought the DME number is on the stock chip? Not being the master technician, I was hoping to only go through the process of pulling it once. Does the date of manufacture give enough information?

I dont think the 530 chips were ever corrected. Might want to look into other chips for the 530 such as the JC conforti chip. Works OK for me.

And this is the very reason I asked before ordering....has anybody on the board got the EAT in a 530ia? How's your ride been since installing it? Thanks.

Duey,

Do you have a connection with him? The web site says to email first if you have a 540/530 before you order a chip. I've emailed twice and got back nothing. I'm not tossing $200 into the hopper until I get a response. It sounds like the M60 chip is not totally complete?

Sorry I was not able to reply this week due to various issues arising here. I know I received on email butI'm not sure about two. I'll respond later today.

Duey and I talk on occasion and he has dropped over for a visit when he was in Toronto. Duey sent me an email regarding your question a few hours ago.

It's best to get the number off the stock chip for 530's and 540's.

Two people had the 530iA chip, one sold his car and the other is using it. I don't know if he is in this forum. I'll send him an email and ask him to post feedback if you like.

Sweet, I just passed Mark these part numbers off my DME to confirm what was required for my chip. There was also a sticker on my stock chip when I swapped them but it was the same as the sticker on my DME.

My experience with the EAT chip in my 525i has been all good. Much better low end performace. Less downshifting etc. Gas mileage is about the same, may be a bit better if I do not stick my foot in it.

However, Mark is apparently very busy with chips and other duties and does not aways answer his e-mail in a timely manner. I would do the same.

Just which chip is the best?

I just got done installing the EAT chip in my 90 535 5 speed. Wow so much smother. Before the chip under moderate acceleration if felt like the car was dragging something. Now it fells as if it has been unleashed. Now it is just so smooth and even, better pickup. Under hard acceleration it pulls all the way to the top. I have not gotten to the new rev limiter.

Mark is great to deal with and eager to respond to any of your questions.
You got too get one.

Seems for some reason I cant really find them on your site. Have you corrected the transmission and check engine light problems that the previous chips caused? I haven't heard a thing about these since. I did like the boost in the lower rpm range yours provided.

Hello Mark,

I have sent another email to the (different) address you posted here. I'd like to hear from anybody who has the 530ia and an EAT chip. I'd prefer to confirm the issues mentioned in this forum are not going to occur to me. Thanks.
