Hi Guys,

Just wondering if someone could help me out with the installing the Racechip Ultimate. I know there's a massive thread on the 235 forum for it but this is specific to the 228i.

I've followed the instructions but I get a Drive Train error and that it can't go at full speed and to setup a service.

I've connected as follows:
Cable A to Intake manifold sensor
Cable B to Airflow
Cable C Turbo-pressure sensor

Even if i use the dummy racechip I get the error, so i'm thinking it's a cable issue? The company i bought it from said they have to go back to Germany to get any help and it can take a couple of days.

Was hoping to get some feedback on here.

Thanks.

Sounds like a faulty tune

It was sorted thanks. Their instructions were all wrong.

Cable A to Boost
Cable B to Manifold
Cable C to Airflow

Could anyone tell how different is connecting of JB4 in comparing to RC in terms of sensors is? Is JB4 connected to any other or more sensors that those 3 (Boost, Mainfold, Airflow)?

Yes

JB4 connects to the OBD it has access to Canbus ( access to ignition timing, fuel, boost by RPM, Boost by gear, datalogging, gauge hijack, etc...)

It has flex fuel wires for E85 users

EWG addon connectors for better boost control

Compatibility with downpipes, E85, Race gas, Upgraded turbos, methanol injection

JB4 E85 Use

If equipped with the FlexFuel add on connector E85 mixtures may be used with pneumatic wastegate x28i models and the x20i electronic wastegate models. E85 is NOT supported for the electronic wastegate x28i model. When using E85 a mixture of no more than 40% is suggested.
