Hey all,

I recently put a 180 thermostat in my supercharged series 1 (1995 Riviera).
I noticed that on highways, it keeps the engine at the right temps, but in the city it still goes up to 205, sometimes a bit over.
I am thinking it’s when the fans turn..?

Can anyone give some feedback on how to keep it cool during city driving?
Does it involve pcm tune? If so, how would one go about doing that?

I have an elm327 Bluetooth connector and TunerPro on my laptop. Is that enough?

I have my ‘95 tuned with TunerPro to have lower fan on/off temps. It was a little involved but I did make a write up when I did it. I noticed a huge improvement in performance from this alone.


I honestly havent used TunerPro since then so I cant say for sure that everything I used is still available or still the same but hopefully it can help get you on the right track.

Also, if you haven't already, check out the write up I did on scanning/datalogging. It will help you learn a little more about TunerPro. The GearheadEFI forum I have linked on there is full of incredibly knowledgeable people on this style of tuning.
