JB4 for 2018+ AUDI RS3 & TTRS

[Rs3go]

I've just recently installed the JB4 on my MY18 RS3 8V as I have 2 years warranty. I read in one post that I can use up to 23/24 liters (6 gallons) of E85? Is that correct? Thanks for any advice

Hi,

It is fine to run that mix.

It goes into pin 14.
If you talking about the virtual reading its something we have worked on in the past and havent managed to get it accurate so ignore any reading from it.

Sorry to quote an old message, but I'm looking for a good solution to run a reliable E30 mix on an 8Y.

Does that mean even with a physical eth sensor wired into the JB4 we won't get accurate readings?
No problem if so, just trying to work out what direction I'll go (fuelit seems to work well as an alternative, although quite pricey comparatively).

With a physical sensor that can output 0-5V it will be accurate. The Fuel It kit is what the majority of users fit.

Hey Terry.. how does the below compare to an 8v.. say a 2019?

Terry and George did you guys ever dyno the TTRS or the 8V?

Remove OPFs.
Map 4 would be fine

ecu is locked , no read option at the moment !

I have an rs3 8y with locked ecu, running map 4, full turboback (opfs removed)

Nice !

can you elaborate more ? i know only UK company got the option to remove OPF but they force you to buy the down-pipe from them and cost 2k Euro !

how did you manage to remove OPF with simulator ?

My rs3 has no sensors on opfs, just take a look under your car and check if there are sensors or not, if no sensors, just replace them with aftermarket midpipes or custom job

S Hey Guys - Anyone can spot whats happening here ? TTRS 8S- Cooler, Inlet, Intake, DP - Map2. Sudden boost - then no boost. Been a nightmare to log // replicate. Lastest Firmware and Chip (as far as I know) - Replaced OBD2 cable in case.

Form the graphic it appears to be following the trend of what the pedal is doing. Last pull might have a issue but its very low rpm for the car to have build boost as it ends at 200rpm.
