Please explain performance tunes

I must be the only HP tuner owner around here LOL. HP OBD2 device can live log without a computer, stores to the device and then plugged into a laptop/computer to be read by the VCM Scanner/ VCM Editor. I originally picked HP - since my car has straight DP's and Gearhead and all others report on their sites they wont tune off-road and gave into buying HP.

@SHOthyme is correct, it CAN be done without the laptop using the SCT livewire, but it is usually preferred as you can see what is going on in real-time a lot clearer. After a run, I can quickly identify points of concern and even do some on-the-spot troubleshooting and maybe make changes to driving style as needed.

As for SCT vs HPT, HPT is quite a bit more user friendly and the GUI is more intuitive for sure. I also heard (but can't confirm), that it datalogs a bit faster with higher resolution. Matt at Gearhead likes to have his customers datalog with HPT if possible and then he writes the tunes for the SCT (for those customers that have both HPT and SCT). As for what either tuner can do for the platform, the HPT doesn't offer any additional capabilities over SCT. The GUI may look different and be easier to navigate, but the fundamental tuning ability of each brand is the same. They both have access to the same tables for this particular platform (not the case with others).

I've had this conversation with Brad at AJP about HPT vs SCT and he's stated that there is nothing the HPT can do that the SCT can't...tuning-wise. He stated there's really no need for him to invest in the tuning license (which can be expensive for tuning shops) if it doesn't add any real value. This seems to be the reason why many ecoboost tuners still use SCT, despite HPT being more user-friendly. The juice isn't worth the squeeze for them. So I decided to stay with an SCT device as it is the widest supported platform, giving it the most potential options and flexibility.

Thanks for a great comparison - and I can see why now why many choose the SCT. I never thought my HP was better - just gave me the ability in the interface to turn off the O2 complaints and easily. Everyone for legal reasons running a biz needs to declare they won't flip the flags off. So I went with HP and a tuner with years exp. I was too afraid to approach GH - and until I only joined late here, knew about Brad.

I would love to have another tuner look over my tune, just can't get into the off road being an issue.

I did everything backwards - knew I was going to start working on a car that had less than 26k miles that sat - start to modify it - instead of joining a forum like this one, there are a few out there, then find out the routes to take I made my decision and bought the HP. When someone helps you do a tune it costs the customer the license fee for the tuner so they don't pay the tax. Which only means I spent more on the long run.

I loaded the LiveWire device with my tuners config file and logged using the LiveWire device itself but the fuel rail pressures are way wrong. Maybe other data is wrong too but the basics seems correct when compared to a PC log (MAP, rpm, speed, AFR, spark, IAT).

I wish I found this site late last year..... it's title says HP - which I know how to do - however also discusses the SCT x4

For reference, of course...

You will need the device and a laptop to datalog your vehicle....at least to do it the right way.

Any recommendations on a laptop that won't break the bank? This tune is probably the only thing that it will be used for, so I don't need a bunch of bells and whistles.

Ebay, nothing special to be honest. Windows 10/11, seriously don't overthink it. Maybe a Best Buy $300 laptop.
