ebay chip

[herbie]

Ok guys, i've searched and found nothing really helpful. So here I am creating a new thread. I have a 1990 325is, so it has the M20B25. It also has the 525 Bosch DME. I bought an ebay chip for some power gains. When i installed it, it gave me noticeable power and the rev limiter was raised to almost 7000 RPM. Everything was great, the car drove great. but the problem was, the check engine light came on. Fearing that it might hurt the car in anyway, I installed back the stock chip and the light was gone, so was the extra power, responsiveness and the rev limit was back to 6500. My question is, would running the ebay chip hurt the car in any way? i know i know i get what i pay for, so spare me the lecture. All I want to know is if it is still safe to use until i get enough money to buy the proper chip? thanks in advance.

That rather depends on what fault is triggering the light. If your TPS is good, a stomp test will pull up the fault codes.

Are you sure this chip was meant to be intalled in a 525 DME?

See, that's the thing, i am not sure if the product i got is compatible with the 525 DME.

here is the info

oh oh oh pick me!
ask the ebay seller.

[herbie]

i just asked the seller, waiting for his response, if not, it's 20 dollars down the drain. Do you guys think the Miller induction kit is worth it? would it really make my car more lively?

[devon.818]

miller MAF and do your own CAI.
i have the miller MAF and dont really think its all that...

[herbie]

hi devon, you dont think miller maf kit and chip wont make a big difference? so, in your opinion, it is not worth it?

if you want set it and forget it, go with markD, turner/Conforti, dinan, etc. if you want to tune your set up specific as you add more parts down the road go with miller. theres probably over 100 chip threads, in the archives, on the m20 alone.

it's probably getting a CEL because the chip is a rip off of another brand (like Mark D or JimC).

They just read the other guy's chip and burn it onto a 50 cent blank, then sell it to you for $100 or whatever. Now do you feel ripped off?

[herbie]

thanks for all your help. chip is out the car, saving up for a legit one, but lusting for the miller induction kit.

again, thank you guys

Have you ever copied a chip before? Do you know anything about it?

Copying a chip won't magically add a check engine light.

The check engine light was most likely on because the ad says the chip is for the 173.

Honestly you can just buy a 173 ECU and put it in along with the chip. I would run it if it were mine. You can pick up a 173 ECU for about $50 shipped. If you decide you don't want the chip anymore PM me and I'll buy it.

it can if they don't flash it properly, don't do the checksum properly, etc. etc.

speaking from my own similar experiences I've seen all sorts of strange issues from a flash that didn't go quite right.

plus you're still directly supporting theft.

Guess I don't know much, only used a chip burner and software first hand.

Yes, you know me. Total criminal. STFU dude.

[nando]

WTH?

if you want to burn chips in your bedroom, I don't care. but if you're copying a JC or MarkD chip or whatever, you are stealing. There's no way around that. It's much worse if you're also selling them to people.
