Hi All,

I have been doing the AFR Fundamentals course and the other associated content here on HPA, I've Owned JDM cars rebuilt plently of Rbs and SRs but this is my first time getting into tuning, i am currently tuning a S15 that has a SR20DE +T Autech, using a Haltech 1500 elite, WB1, 980cc injectors ect ect, it being a N/A motor i'd like to think i've been very conservative on the ignition map, and feel i have the fueling map pretty close as its all been road tuned (no access to a dyno)

Basically id like to have someone just check my log and gain any feed back as to how i have done, the car drives and feels great, but i am looking for any feed back on how to improve myself

Thank you to anyone in advance for any advice :)

P.s i met Andre at GTR Festival and even got a photo with him :) after chatting to him i pulled the trigger on doing your courses and the content is bloody awesome and ive never looked back, i have enjoyed the learning and gained new skills that i never thought i would have.

First, I'm not sure your Manifold Pressure sensor is calibrated correctly. The Measured Manifold Pressure goes from -87 to 65 kPa.

I think you have the opportunity to improve your fueling. I would suggest turning off O2 Control, nail down the full throttle fuel in the 3000-4400 and 4400+ areas (seems to be a step around there). Then move onto more part throttle acceleration runs to help refine the shape of the fuel table.

The MAP sesnor is directly into the ecu itself via a vacuum line from the manifold and uses the factory 3bar ecu sensor, I updated the firmware on the ecu, I’ll double check that’s it’s the correct calibration but I don’t remember if you could calibrate it. I’ll check that today. The Autech have a high compression rate 11.5:1

thank you for taking the time to have a look and give feedback I really appreciate it
