The Dinan Flash has been out approximately 4 months. So is Dinan holding true to their "error-free" bravado? Have any Dinan Users experienced a CEL/Limp? Thanks for you input.

5 moths???? WOW time goes by fast...it seems more like 2 moths to me

You are right I stand corrected, 4 "moths".

How can it throw a LIMP/CEL if it is flashing the ecu? It is not a piggyback, but re-writing the code.

I've had mine for 3 days now. Too early to vote.

Is this a serious question? If so, you do know stock 335i throw CELs and go into limp mode.

In few days, you should be in for a pleasant surprise in power.

No problems here...however I will say that mine has been stored in the garage most of the winter.

Are you serious with the question? Do you understand why the 335 throws CELs/LIMPs? If you reflash the ecu, then you re-write what throws the LIMPS/CELs. Unless you have a major failure there should not be CELs.

The piggys try to trick the ecu into thinking it is operating within normal parameters. Since they must work within the framework of the stock DME, then have a different set of rules to work under. A flash re-writes the rules.

Dinan doesn't alter the fault recording algorithm only emission part of it; actually no tuner would want to do that(no gain but alot of work really for what?). So if anything is wrong with your car(O2 sensor bad, turbo wastegate, fuel pump etc) it'll throw CEL.

in S/W we have what we call BIT(build in test) which is alive in multi-thread CPU monitoring all kinds of stuff this is the part that Dinan wouldn't touch. And it report back to CPU and CPU will write it as code based on severity into flash so tech can check what part is going wrong. Hope it helps.

I would assume it changes the boost target not reached LIMPs and such though right?

Yep, stuff like that.
really the CEL on Dinan if any would indicate a bug on their S/W. Only time will tell how good they understand the original BMW code (cracked op-code version since they don't have access to the source code).

Sounds like we are on the same page.

On a side note, the many options available are just fantastic for this car. I think the 135i will just make life even better as more competition enters this thriving market. The N54 tuning world is just phenomenal and getting better.

How did a discussion of piggybacks get crowbarred in this thread? The point of this post was to ferret out problems with the Dinan Flash. Nothing more, nothing less.

Thank you for providing clarity. I did not have the patience to post an explanation.

lol at the "Dinan haters" who appeared in the poll results. at least you guys are honest, sometimes.

[M4TW]

I'm getting the FLASH in about a week, so I voted 'no' because I don't want any problems.

j/k

[sparkyg]

Gotta love the haters honesty, oh well.

Lookin' forward to the Stg 2 FMIC

[jtmccabe]

I like how the one guy who has supposedly had a problem didn't post the details. Think he might be in the hater category.

i was going against it all, i LOVE dinan, dont get me wrong, and I for one dont think its overpriced(except for their oil cooler!!) but this thread is intentions are otherwise.... dinan will not throw codes. ppl state that stock 335 throw codes.... great then that same stock 335 gets dinan will still throw codes...

DInan is a good tune, if you PURCHASED the car. Get the turbo tuner is you leased it or are thinking of keeping the car short term, unless of course, you dont care about money

Spring is just around the corner.

It would be nice if he did have a problem to supply details. Maybe he did not know it was a "public poll".

You won't be disappointed, although what took you so long. I have seen barges move faster than you

I think you are reading into this too much, I was curious to see if Dinan users had problems (CEL/Limp or otherwise) with their car. Dinan users are typically quiet here (although there are exceptions such as myself) so I was attempting to elicit information from the shy owners. I did not intend to offend anyone (nor have a discussion of the SSTT).

Unfortunately, due to your frustrations the poll is incorrect.
