JA Custom Tuning Custom ECU Tuning/Remapping for cars, vans, trucks, buses & tractors. Worldwide tuning File Service. Mileage Correction.

Custom Exhaust works - Res backbox delete, dual/quad exhausts. Mechanical & Electrical works - brakes, Servicing, trackers, dashcams At JA CUSTOM TUNING we specialise in developing bespoke tuning files in house by a master file writer with genuine state of art master tools and tuning softwares. In contrast, 80% of Remappers are not master file writers themselves, which means they can't open or edit the files data themselves. We develop the files in house on the spot according to the owners driving style and engine's response. We also have dyno pro for serious enthusiasts wishing to get their vehicle tuned on dyno with exact figures. We also remotely tune files for other remappers as file service worldwide. We offer all sorts of deletes and add ons including DPF EGR O2 Lambda DTC CAT Rev Limiter Speed Limiter NOX Hardcut Sports display on bmws, POPS & BANGS Even FLAMES for our customers and other remappers for their customers

F87 M2 comp in for Ecu obd unlock and cold start delete. We’ve done many of these here’s just another one. Give us a shout If you got a s55 with obd locked and want to get it unlocked for mhd or bm3 Or even tuned by us.

As shown in this video. Lot of things needs removing, not only that, gotta be very careful removing them too especially charge cooler as you have coolant tank sitting above it, coolant lines and vacuum lines above it on the left side and coolant line secured to the charge cooler. as you can see we also covered the charge pipes ports with cloth so nothing falls into it. A small lack of attention could open doors for big mistakes. We’ve done lots of s55 Ecu unlocks for bm3 and mhd including tuning them oursevleve.

Audi s4 b9 with zf8hp gearbox in for gearbox service with genuine zf parts Suplly and fit. Coolant flush and oil change. Everything carried out successfully. On the Audi zf boxes it’s abit more headache to remove the pans on these as the transmission mount blocks it.

How often should you service your zf gearboxes ?

Zf recommends 60-80k miles

We also service other gearboxes. Give us a shout if you need gearbox service

2.0t in for double backbox delete and pops & crackles manually as he didn’t want it to pop all the time, with this, he can control the pops with throttle. We can do this manual pops with throttle control pretty much on any car however the automatic pops are usually better sounding and more consistent.
