The dealer CAN see if you have exceeded the top speed set by the limiter of the car. Cobb, to my knowledge, does not remove that when you remove the tune. So in the case of a blown engine, and they start digging around to find you were doing 180mph, then they could certainly make a case that your engine was modified in such a way that allowed it to blow. Removing the tune removes the top speed limiter default, but I'd love to hear directly from Cobb if they reset any historical data stored that shows your cars speed.

I think the point about leaving mods on vs taking them off for a dealer visit is, while you may get service and even minor warranty work done with no problems, your VIN may go into a "detected tune/mod" database so that in the future if major $$$ things grenade, BMWNA can if they wish deny coverage (not the dealer nor even your friendly SA has any say in it).

I was told explicitly that a Dinan tune (installed by the dealership's own dinan franchise) would void the existing CPO automatically. I.e. the moment BMWNA was notified of Dinan tune installed, no more CPO. Car was then still under original manuf. warranty.

It's pay to play for sure.

incorrect hpfp was NOT recalled for ALL n54's, my car has had neither recall on injectors or hpfp yet ive had BOTH go out on me

^ Good question.

Also, does Cobb adjust the rev limiter?

A long time ago (prior to injector recall) I had brought my car in several times for cold start misfires. The dumb tech couldn't figure out what the problem was, even though I told them several times that I was positive it was the injectors. I brought my car in stock, but left my meth lines under the car and controller in the trunk under the mat. They had no problems with this until about the 4th time I brought my car in for cold start misfires (they kept saying it was normal - complete BS). At this time they said they refused to do any work cuz I had modified my car. Basically, they were using it as an excuse to not fix their multiple failures as a mechanic. My warranty was "voided". I ended up replacing the injectors myself and lo and behold problem solved.

After that I just started bringing my car in fully modded, FBO + meth. I have had maintenance done, front sub-frame replaced, power steering pulley replaced, hpfp replaced, injector recall checked out, windshield replaced, radiator vent hose replaced, and some other basic stuff I can't remember. All of this stuff can be argued that my mods wouldn't have affected it. I doubt they would've replaced blown turbos or damaged block had that ever happened though.

I'm pretty sure the recall on HPFP is for all with the older part #s. They replaced mine without it ever actually having problems (40k miles?). I miss my original HPFP, he was strong. My new one scares me all the times with long cranks.

Injector recall is based on a certain batch of injectors. I've replaced bad injectors post recall that BMW said didn't need replacing.

bmw pulls up recalls based on VIN numbers not on whether its a faulty product or not. my VIN pulls up no open recalls, but i had hpfp replaced under warranty and had injector replaced out of my own pocket

AFAIK,
The injector recall is based on a barcode # on the actual injector. They physically take out each injector to see if they fall under the recall. So they can't find it out through VIN. This is why some people only get a few injectors replaced and not all. It was a batch that probably was out of tolerance.

As far HPFP, bringing up your VIN will show information on build date and whether your car has already had the replacement. This could tell you whether you have the bad part# of the HPFP. I would be surprised if any n54 prior to 2010 is still on the original HPFP and doesn't have an open recall.

bmw cannot even scan injectors on a car that doesnt pull up a VIN recall...know how i know...i just replaced injector and bmw couldnt do anything about it. whats gonna suck is when we see the a 335 pass over 120k miles and get out of the hpfp warranty and not be under recall, they will be replacing that out of their own pocket

Did you buy your car new? Maybe they already checked your car for the injector recall with the previous owner. I am on my 3rd set of injectors, the 3rd set I have replaced on my own dollar, which some were after BMW inspected all my injectors to see if they had the recall. I know all about these dumb injectors. If your VIN brings up that your car went through a recall, then of course they wouldn't do it again. If VIN was the only thing, they looked up, then why would some people get all 6 injectors looked at and only a couple replaced. Sure they look up your VIN first to see if you are eligible for the recall. If you haven't had it, then they go to the next step which is scan the injector part #. For HPFP, when they pull up the VIN they can see which HPFP you have. They use both the VIN and the part# to figure out whether they should replace the part. Does that not make sense? VIN is the first weed out of cars that won't need the recall, then part # weeds out the parts that don't need the recall.

Any idea what the part numbers for the faulty injectors are?

I'd like to check mine myself without going to the dealer.

100000 this is what I have been worried about and what's holding me back from my Cobb purchase don't want the rev limiter set to 7200 over the factory 7000 can't they see that engine has been over reved that way thus meaning theres a tune even if the codes are cleared during the uninstall?

I don't think this is correct. If you replaced your injectors before the recall and the old parts were gone, then that was likley the issue. If you had kept the old parts they likley could have scanned them and potentiall reembursed you. Thier scan is only knowledble of the part SNs that are affected by the recall and they don't keep an association of exact part SNs to VIN for this purpose. If my assumptions are true, you might have a shot of getting someting back with a letter to BMWNA.

This is the ONLY reason I have yet to buy a Cobb. I love the ease of use and the ability to quickly add/change maps BUT everything I have read has said there is no real reason to rev that high (no power up there). Why do this and risk tipping off dealer?

FWIW there have been a handful of people that have had Cobb and had their turbos replaced or other major warranty services performed.

trust me dude ive talked to about 30 different people from BMWNA to 6 different dealers...

i bought it 2 yrs old with 20k on it. if the car isnt under warranty and the VIN pulls up no recalls they cannot even replace a recalled part. I had the car at the dealer this week and even though i have bad injectors and hpfp my "VIN" pulls up no open recall campaigns so bmw wont do anything

I think in one of the recent Cobb updates they removed the raised RPM limiter.

I can't find a specific mention for it but before the v203 maps were released a few people were getting limp modes at the 7200 rev limiter and a few days later Cobb released 203 saying they adjusting shift points to make it smoother on an AT. Rob@Cobb said "The map changes are to the AT rev limits and how smooth the shifts are."

Also, all logs I've done stop at 7000 RPM.

Edit: Found it. If you look at the PDF for the v203 map notes "this update reverts the stock limiters to stock settings for AT vehicles"

There you go.

If you look at the top of each map its says either stock rev limiter or raised rev limiter. The drive maps are the only ones that say stock. But i believe the rev limit is only raised on Manuel tranny's. I'm running stage 2+ sport with AT and haven't seen it rev past 7k rpms.
