Procede V5 in JHB (N55)

[Twinz]

Hi stealth. Please take my advice from this point. Dont WOT the car for one more run. Remove the procede. Make sure everything is back to stock. That loud ticking sound, is unusual and maybe dangerous to the car. When back to stock, get someone to read the codes and give you a print out for your record.

Fill the car with normal unleaded and drive it around for a day or two under different conditions and keep notes on how it behaves. But dont put the tune back in.

If all is in order after a day or two of varied driving, then take it to xcede or chiplogic. Let them reinstall the proceed and check everything is okay before you WOT it again. If it still fails, then throw the tune away. Your car is far more important than risking it with a tune that maybe faulty.

Okay i wont go WOT.

However when i put the car back into stock map i have no problems what so ever. No ticking, no stuttering nothing,


Ive done a code read and there are no codes being thrown,
It is obviously the procede causing the problem, i will check the connections nw again and if i cant find anything i will remove it for now as i have service in 2500km's. I am thinking of returning the procede to them for a refund because this is ridiculous.

I think this is a very good decision. So many things can go wrong when a piggyback tune starts giving problems; irrespective which tune it is. :thumbs:

Umm.. just had a look at your log and there is definitey a DME code being thrown, look in column G, code:12253? Remember the Procede reads the native BMW decimal code and not the Bavarian Tech one. Am checking but I cant find that exact code yet, but think it may be fuel pressure related as codes that are close are all fuel pressure related? Check this link procedetuning.com/BMW/n54/downloads/.../BMW%20Codes%208-17.xls Will see if I can find it on the US sites, maybe email Shiv as I'm sure he'll know?

Furthermore I think you have CAN clear active which keeps clearing the code before you can read it with the BT cable? Are you reading in MAP 0, otherwise the Procede will interfere with the BT cable? If you can, taking into account the recent ticking noise, do some higher RPM logs as changing before 4000 RPM wont show much? Try do a run staying in 4th, right from the bottom rev range to redline, can be very difficult to do that in an 6AT without automatically kicking down a gear

Okay so I removed the procede and I'm still getting the rattle and jerk at high revs wen accelerating so I'm going to keep the revs low wen I drive as I find it drives normal. Car is going in to bmw on friday so we'll see wat they say

 

[Twinz]

Your fuel pump may have gone & some injectors...

May also be a good time to replace the plugs :thumbs:

Surely there would be a check engine light by now or limp mode?... Idle on the car is fine and nornal driving seems fine its just on WOT the car stutters as revs build and once car is boosting full (stock)

Very wierd

 

[Twinz]

The car will not necessarily throw a CEL for the notorious HPFP...it may only
trigger a CEL when the car literally decide to get stuck on the road.:thumbdo:

Hope you get the problem sorted soon.

 

[Stealth135i]

Thanks Twinz

Will keep everyone updated and will start a thread listing the symptoms and findings after friday so people can refer to this after its sorted!

I was also speeding a bit the other day with the procede ... and also heard a funny noise at high revs ... and all of a sudden (!) pitched up on my display and the car went and stand .. put it off .. removed key ... and in again .. stock map .. everything fine .. Thinking of throwing away the tune . As twinz said ...The car worth way more than the tune ... we will jus have to wait for a flash tune i guess ...

Was this on pump fuel? What start boost & start ign corr Procede user settings are you running, could be that they are too high for 95 pump at altitude? Perhaps go back to the old standard V5 maps and see if the same thing happens, Initially I had hassels testing the beta dynamic ignition correction maps? Apparently these are now sorted though

I sent Shiv@Procede an email saying that after 7 months of crap trying to get their tune to function and install correctly followed by now a issue with my car that i want a refund,

his reply, is "Before you do anything, take the car to the dealership for troubleshooting. I'm quite confident that the noise you are hearing is unrelated to the Procede. We cannot issue a refund if nothing is wrong with the units. We have sold hundreds of these units outside of the US and no such issues have been reported. "


:argh: R you kidding me!!!! This is honestly the worst experience with a company i have ever had, i will keep you guys in the loop because people deserve to know how Vishnu Tuning operates as it is disgusting!

 

[Twinz]

Stealth...very frustrating indeed. :nonono:

Here is my big BUT:

The fuel pump/injectors/plugs or a major boost leak, could be unrelated to the tune and have often been found to be unrelated. Sometimes running higher boost aggravates a problem or brings to light a problem that may have been there before. So, it is quite possible that the problem existed before you installed the tune.

Thats why i recommend a boost gauge for those running stock boost as well. It is possible that your car was not boosting its full stock psi due to the latent issues above.

I know it is frustrating when something does not work out of the box, but lets see what BMW's diagnostics find and make a call from there.

It is concerning that there are other procede users with simillar issues and Vishnu needs to be informed about this.

Understandable, but the fact that 7months of problems and a tune that they couldnt get working i would have liked the option of a refund even if they asked me to wait for results from BMW as they sent me another unit which doesnt work and which harness is faulty so they cant say their products are perfect. For now will just have to see what the damage is tomorrow.

Sorry to hear about your ordeal, rather wait and see what BMW says. I remember you having issues with your MAF the last time as well. It might be something small and unrelated to the tune as if its doing it stock then the tune cannot be blamed. Best is to log the car. Have you used any OB in the car?

When running a tuned map, V5 has CAN intergration and one can do a full log of what boost the DME is seeing and what boost the Procede is actually delivering without a boost gauge. Not sure if logging still works on the stock map though, as all signals pass directly through? When I finally get my car back I will test and see..

Highly recommend when Stealth gets the car back from BM he sees a tuner like Sherwin to set things up properly. Dont want to give Procede a bad name unnecessarily, I know Sherwin has done a few N55's using Procede and I haven't heard of any issues??

 

[George Smooth]

No codes are thrown, only 2 maps for the n55.... anyone able to read logs?...

It stutters on full accleration on both maps, its a very loud ticking?.... Any one with n55 procede care to send me their user adjustable settings that they are using on their procede so i can see if it stops this problem, at least until i hear from PRocede and see what they say.

The ticking is loud and power starts to cut but resumes.......

I put some octane booster in when i installed the procede could it maybe not be doing well with the tune?. I dont know how the tune operates without the octane booster as i never tried without it.

I will attach the log i took if anyone wants to view it.

here are the logs

I finally had time to look at your logs. The first thing you should do if you decide to stick with the Procede is turn auto tuning on for now and see if the problem persists. At the point in the log where you got your misfire the car is running 1.11bar boost which is too high in my opinion for a car without mods.
The fault you are showing is a crank sensor fault, the cause of this is the tune and is something that is being rectified asfaik although the fault should not cause any driving problems. On the N55 you cannot log the fault codes in the same way as the N54, what you have to do is plug your laptop in, check for faults using the cruise control stalk and the faults will appear in the window on the right hand side of the user interface. What you might be seeing is a long term stored fault in the log.

Car came back from BMW yesterday they changed the Spark Plugs and did a software upgrade and the noise is gone, installed the procede and its working fine now :thumbs:

Cool, take some advice from me and avoid octane boosters as well and keep the unit on auto tune.

GS, do you really think the forumites will take our advice...:=):

They wanna boost 23psi...
