JB4 Fitting

Post by Locko » Thu Dec 06, 2018 11:46 am

Hi all debating between MHD and JB4 and thinking about buying a used one of ebay is there any good companies that could fit it and go through everything in the northwest? Id love to go to chiptune but it is miles away from me. Thanks

Jb4 you can plug in yourself, not sure why you would want to pay someone to do that though?? Personally and proven by a fue members that mhd is the better option and again is done by yourself

Where abouts in the North West are you located.

I'll give you a hand fitting it, really easy install.

Because id rather get them set up correctly go through the maps and dyno tho car, so to make sure everything is running correctly and no misfires id say the expense is well worth it.

What other mods have you done?

If running a sports cat it might be worth getting a map 6 setup on dyno but I'd personally choose the MHD route as the maps run alot smoother and bring the power in better.

I'd go MHD stage 1 or pick up a cheap JB4 if the car is standard.

I personally wouldn't run the stage 2 without the downpipe and an uprated chargepipe and intercooler.

What car have you got?

Fully recommend MHD. Had mine flashed for the last 4 months. Fantastic mod - just don’t forget to upgrade your boost pipe with whichever you decide to do!

Hi Neil would you recommend doing that even for a stage 1 tune and if so what make would you buy and are they easy to install?

My boost pipe failed after a couple of weeks at Stage 1.
Once you have a look at the original one you’ll see why, it’s made of very soft plastic that just splits where it joins the inlet manifold.
You can always take your chances but I’d keep a roll of gorilla tape in the car just in case it goes when you’re miles from home.

I chose MHD for several reasons really. I just bought a simple Android tablet and the required cables for £60 via amazon. Download the app on google play - if you’re already an amazon user than you’ll be well versed in this.

Hardest part was actually buying the maps. This was because it was my first purchase on google play and as it was for a large amount it placed a security block on it. Had to call the help line etc.

Once you’ve bought the ‘flasher’ - which is what you only need to do once and is what ‘unlocks’ your ECU. Bought the Stage 1 map.
Once you have that you can make changes, such as cold start delete, V max limiter removed, exhaust ‘pops and bangs’. Childish I know but I like the adjust ability.
That plus MHD release updates to their maps that fine tune them so they are smoother and more options are available each time.
When you take your car in for service you can also - reflash back to stock. Probably pointless but gives me a little piece of mind and takes about 4 minutes to do.
I did lots of research and learnt how to use it first from watching YouTube videos and reviews and I’m very happy with mine. Noticeable difference in power.

Thanks very much mate what was the boost pipe you decided to purchase and I think I’ll deffo go down mhd route for the ease of it I was just abit worried about damaging my ecu. Gives me a lot more confidence and I’d love to get rid of cold start especially if I get a sports cat haha!

Is there a reason you arent considering a remap?
Once this winter has passed I'll definitely consider a remap, I didn't realise the chargepipe was a weak link, is it difficult to upgrade? Costly?

Forge is probably your best bet.
