`98 T/A hypertech tuning RFG or NON RFG?

[ls1robert]

I have a `98 T/A a4 and i have the hypertech tuner III...i have it for my 17 inch tires and 3.73 gearing, i also have it set for 160 thermostat and the rev limit of 6000 RPM....it asks if i want engine tuning RFG or NON RFG...what the difference and whats better?

[Mr. Luos]

Oh god....hypertech.
Use it to change gears....and NOTHING else. Then ditch it for real tuning software.


Why did you lower the rev limiter? Or did you change shift points not limiter?
Or maybe I am too used to the M6 car....stock rev limiter being 6200.

I don't know what the hypertech RFG or non RFG tuning is, but regardless its not beneficial. Hypertechs are a waste for LS1s.

no my car was shifting at 5800 RPM because my knock sensors are garbage (look at my other thread i started if u wanna help) but yes it was shifting at 5800 then i changed my shift point and added 2 MPH then it shifted at 6200 RPM but it sounded like it was over revving....so i made the shift points stock and changed it to 6000 RPM and sometimes it still shifter lower....so rfg or non rfg? and y does it suck?

[Mr. Luos]

Very little control. Basically just able to change the ratios and limiter.

Otherwise it has set tuning changes to add power....which include very little other than taking out a little fuel (lean = power) and adding a little timing.
Neither of which should be done unless you can monitor the levels.

It leans out the motor to gain a few HP, and by a few HP, we are talking 5 or less. 5HP is not worth the risk of blowing your motor cuz it was running to lean.

RFG = ReFormulate Gasoline
It depends on your state laws as to whether you have it or not and it should be listed on the pump if it's RFG.

I have a Hypertech that came with our car. Like you, I used it to change the fan settings for a cooler thermostat. I then went with a Frost mail order tune after some mods. Right now, I have the Hypertech attached to the cup holder and use it to monitor engine data. Since the temp gauge in anything other than a '98 F-body is basically a guess, I always have my engine temp on display in the four (4) gauge screen. I rotate other data, such as IAT, short term fuel trims, MAF, knock sensors, engine load, torque converter slip, command air-fuel and such just to keep an eye on things. The full screen gauge display, which shows 12 or so items at a time, is simply too difficult to read while driving.
