Hi all,

Hope that somebody can give me a definitive answer here. I'm running an Evolve map on car at present but I have a JB4 sitting around doing nothing and I'd like to know if I can fit it and switch between maps.

My concerns are that when the JB4 is active the Evolve map will interfere with infomation being sent to JB4 and screw things up etc.

Dont ask why I have both as it's a long story involving the dealer wiping out my Evolve map and then me having problems getting the new map created by Evolve flashed to ECU. So I thought I'd go down the JB4 route and bought one but then I had some time and patience and managed to successfully upload the Evolve map to the ECU and it's all working fine now.

However if it's possible I would like to try the JB4 and it's features and maybe compare how the two feel.

Cheers

AFAIK, not both of them on together.
I read your post somewhere that you upload the evolve map yourself.
In that case, put it back to stock and try JB4 for few weeks. And then try evolve map again and see what suits you.
If time and funds allow, I'd add Cobb on your list. (sorry, giving you expensive suggestion).

I have driven JB4 and cobb enabled 335i cars and felt cobb was more aggressive. But thats from layman point of view.

Hi Sam,

Yes that's what I'm talking about having them both of them on together.

Yeah I flashed the ECU myself with my Evolve-R cable and software but due to issues (both dealer and Microsoft created ) I'm not that keen on flashing it back to standard and then maybe reflashing at later date. Although now I've got things set up correctly it should be fairly smooth.

Yeah was looking at a Cobb but it's just more than I can really afford atm.

Cheers

Try to read the current map and if it reads, then give it a go mate. You will never know the true difference bw jb4 and evolve map....

[jimborae]

It reads the maps fine and I've got verified working backups etc. The issue was flashing the Evolve map and the security key exchange when flashing. It failed on 2 attempts which then leaves the car in a non working state till you do an ECU recovery back to standard. On the 3rd attempt I did it on a completely clean fresh build laptop and it worked like a charm. However if things go wrong then it takes over an hour to get you back to original state and that's time I dont really have to be messing about with things.

Just flashing the Evolve map takes about 30mins. so if things go ok then all is hunky dory, if things go wrong then I start getting grief from SWMBO along the lines of "how much longer are going to be messing with that bloody car? It's fast enough as it is!"......She drives a Kia ffs.

Story in every other house. Well wait till she goes to her parents and that would be your golden chance

I can see where you are coming from. If things go wrong, we are talking about hours to troubleshoot. Good luck if you ever decide to try.

Sorry for the hijack but im mapped by angel tuning and looking at the Cobb V3 would it work on mine as its mapped or would I need to be flashed back standard .Thanks

I have not owned 335i. A logical guess would be getting engine management light if you add cobb at the top of map. You already has map and if Cobb has no ability to detect that, it will try to do its job....and be ready to get engine management light.

[AlanYoro35i]

We know that you can run both with cobb and jb4 but not sure on evolve maps.

[gazz1971]

Will it be ok then and just over write the map that's already there .? why would the engine management light come on ? sorry for so any questions does the car need to have a standard map on it before I can load the cobb up ?

[kev335i]

Jb4 Does not flash the Ecu it's a piggy back tune so I'm sure there will be issues there. It can be used in conjunction with the bms back end flash allong with others n54tech is probably the best starting place to learn more. As for Cobb this takes a copy of your standard Ecu data and flashes the Ecu with the Cobb software and map. If the Ecu is already mapped with some sort of protection on it I would imagine the Cobb will fail. From what little I know I believe you will need to flash back to standard bmw then install Cobb onto that. That said for a definitive answer ask Terry about the jb4 and email Cobb support about the Cobb.

[gazz1971]

Im led to believe the standard map has protection a code that changes every time you start the car so I was told by the mapper. If the Cobb over writes the current map will it matter what map that is .

Yes - go to standard first

[kev335i]

I doubt it changes every time you start the car some how maybe the imobiliser part does but not the protection of the Ecu. Cobb will have spent a lot of time and money cracking the default bmw encryption I very much doubt they have done the same for all the encryptions used by all the various tuning companies. Same for Cobb if u flash car with Cobb can u then put another tune on top? But if try it and let us know.

Yes you can stack JB4 on evolve. The only reason to do this is to get gauge hijacking and to run meth...

You would need to run a bespoke map in the latter case and map 4 in the former..

Personally I'd only do it to run meth.

[gazz1971]

Il have to ask Angel tuning to flash back to standard then install the cobb .My reasons behind this since having the catless downpipes ive had the EML on angel have been back twice and the same fault P0420 cat before thresh hole bank 1 drives for around 40 mile then on it comes . The cobb has a cure for this im led to understand .

Correct but I believe it's only on the stage 2 map or race maps by default.

[gazz1971]

Its loaded with the stage 2 maps I believe ive just bought the one off here the V3 .

[kev335i]

You can load all the maps for your Ecu from cobbs website it also lists octanes and supporting mods required for each of the maps. Although a ptf etune seems to be the best way of maximising the performance from your car when using Cobb.

[gazz1971]

Cool sounds perfect .Many thanks for the replies

To add to what Phil has stated the gauge hijacking is good but running a jb4 just as a meth controller would only benifit cooling IAT's unless your evolve tune is tweaked for the octane benifits of running meth. In which case the aquamist hfs-4 with its built in failsafes are another route for running meth however you wouldn't benifit from the gauge hijacking.

[phil200tdi]

You can add more boost on JB4 too whilst running meth = More power..
