2023 Recommended Tune Options

Full exhaust meaning headers and cats as well? If so, what headers/cat setup did you have?

Did you get more mid range torque?

I'm interested to know as well. Very impressive numbers.

My car made 336whp and 261wtq with just eventuri intake and full exhaust on his tune.

What kind if performance gains have most people seen after getting tuned by Hassan?

I've got a wideband in one bank of my headers, (I know both would be better) its and innovate LC2 and works great.

I use a Serial>USB adapter to plug into the laptop and testo can pull the WB info right along side other info via the OBD port, works great and was easy to setup.

This is a stupid question...I have the BW race which has a bung at the y-merge. I can install a wideband sensor there...what else do I need for the purposes of tuning? I don't plan to leave the sensor in.

Ideally, you'd have an aftermarket ECU which would be able to read wideband sensor data; otherwise, the other option is the gauge pod which certain kits include. There also might be a kit that includes a USB cable coming off the sensor which you could plug into a laptop and read/store the data for the tuner. After tuning, the sensor can be removed unless you want to monitor AFRs.

The stock ECU does not use wide band O2 sensors. Preferably, one would add two WB sensors to the unused ports on an aftermarket set of headers or one WB downstream in a single x-pipe style section 2 if they are running that type of section 2. This would give the tuner the best ability to dial in a tune for a specific engine configuration with x miles. That being said, Hassan and Paul have tuned so many S54s that they have pre-calibrated tunes (already tuned on a dyno) for most setups and making some minor adjustments on a dyno using a tailpipe setup should result in a pretty optimal tune. To get closer to perfect, one would have to add the dual aftermarket WBs.

I have swaintech coated megan headers with the BW race exhaust. I flashed in a canned PCS tune - 311whp which was higher than I was expecting.

Not sure if its an issue but the swaintech coating is starting to flake off in a few places. Not sure if its an issue, I know the coating is supposed to be kinda ugly. I would be very disappointed if it was an issue.

I don't think there are any worthwhile off the shelf / plug and play tunes, unless I've missed something.

It depends on what you consider a canned tune. I have a PCS tune. I send money, he send files, I upload the file. I guess it depends on your goal. I just need something easy and relatively safe at this point.

I had an Evolve tune on it before. The good news is we aren't beholden to Evolve and Active Autowerkes and shark tunes any longer. We have some great options now.

That’s good to know. Hassan is very responsive, so go with HTE. Close thread pls.

[avusblue]

I have PCS also for my CSL/Map tune, and I've been very happy with it, since we are on the topic, anyone got a hold of paul lately? I emailed him for a retune, never got any response back

What’s the general consensus on EPIC tunes? I had Randy remotely tune mine a few years ago, I've since added a few things and also fully rebuilt the motor. I’m wondering if it would be worth while having him take a second look to make sure everything looks fine.

tbh, Idk crap about tuning or the process involved

EPIC should be fine as they have been tuning tracked cars for quite a while. Yes, if you changed intake, cams or exhaust, you'll want to have him make adjustments as the air fuel ratio will be different.

are the tuners not pulling the WBo2 signal from the data in the ECU when tuning on the Dyno? The 'tailpipe' setup at dyne locations are notorious for not being the same as the ones in the upstream of the exhaust due to heat differences.

you should be able to pull the short term and long term parameters out of the ECU when tuning.

Same question -- Does he only offer dyno tuned options?

I run a PCS canned tune for my CSL/MAP and SSv1 setup. If you have one of the common configurations like that he’ll have a good map for it from previous work. Mine idles perfectly, zero hesitation, no issues over thousands of track miles so far.

Thanks for the input. I'm thinking of adding a wideband. Any suggestions would be appreciated. I came across some awesome custom gauges from kokgo20. Hopefully he still makes them. Sent a pm for more info.
