Remaps / Piggyback Tuning boxes

SteveSmith · Post by **SteveSmith** » Mon Dec 05, 2016 11:57 pm

Hi all,

I have a good amount of experience with remaps on the 1.8 20vt VAG engine but never a BMW.

I've used Revo and AMD in the past.

I'm looking at tuning options for my 28i and wanted peoples opinions and experiences.

I'm unlikely to go any further than the map / panel filter.

Are these piggyback boxes safe?

Will it throw up fault codes?

Can the std clutch on the auto box cope with the extra torque?

Hi and welcome, another 28i joining the crew.

Remaps are always best, but fairly permanent solution.
Regarding piggy back systems - I would recommend two options.
1) JB4: Ideal if you want to go to Stage 2 (Cats removed) - and look at error codes - but not as comprehensive as Carley
2) Racechips: not as feature rich as JB4, but comes with 2 yr warranty - but ideal if you want to keep to stage 1.

With both methods you should get around 285Bhp - and be close to most 3 Ltr cars.

There is no real value in a K&N filter - however I do have one

I'm leaning towards the JB4 as I've heard a lot about them from reading about 135i's and 335i's.

As long as these are safe!

I know the panel filter won't do anything, but it's nice knowing it's there!

I don't want to make the car loud or anything so I don't fancy removing cats or fitting a loud exhaust or anything. Power around 290-300bhp would be perfect for me!

and for anyone with a 20i, Superchips can get you upto 270bhp apparently?!

JB4 is the only way to go....AMEN

Please be aware that with the JB4 you need to attach via the canbus. The OBC route is not supported on the E89 as it's a E class car, the OBC only supported for F class cars.

Regarding reliability I had no issues for nearly three years. Just keep to map 1, since you sticking to stage 1

You need to Tap wires into the Canbus which is located in the DMU box - so it is visible that an JB4 has been installed - it is an intrusive MOD
