Autotech HPFP with Revo Stage 1 - SPS Settings

(1/4) > >>

Hi,

I'm going to be getting a HPFP fitted with Autotech internals after reading about good gains even without going Stage 2+.

At the moment my Edition 30 just has a Revo stage 1 remap and Neuspeed intake. I assume it'll play nicely with my set-up as others have reported?

Do you think it's worth getting a SPS switch to tweak the Revo settings to account for the new pump or will the ECU adapt automatically? :smiley:

bacillus:
The ecu should adapt but you might still be able to increase the boost a notch with the superior fuelling.
NB You should log the car if you change any settings.

Cheers! :happy2:

I don't have VAGCOM so buying that and a SPS switch just to get a few more ponies will probably not be worth it.

What would I need to log? Fuel rail pressure actual vs requested? I have a phone app with OBD adapter but it only lists fuel rail pressure and I'm not sure if it's requested or actual.

Out of interest what kind of gains are people seeing with a HPFP on stage 1?

bacillus:
If the search button would reappear then I would direct you to a post by KRL where he showed that even with stage 1 on a S3 the fuelling is a bit marginal with the oem pump compared to an uprated one.

Thanks - KRL's original post is below and is very informative however it does not mention actual bhp/torque gains.
