? Anyone running the new Preadator Revision r50c ?

[codyGT]

? I was going to update mine but I didn't know if it was worth it ?

It states that they added some revised GT tunes.

I just got my predator preloaded with r50c, great SOTP gain. I don't know in comparison to the previous revisions as I haven't used them, but r50C is nice!

hmmm....I wonder which one I have, I will have to go check tomorrow.

I don't have this revision, but I am going to get it. Any other comments about it?

is that a revision for the stock tune? if so how can i tell if mine has it? i just got it about three weeks ago?

When you boot up your Predator, it will show it in the upper right.

I went from r50b to r50c and didn't really notice any SOTP difference but still a big difference from stock. A back to back dyno run might pick up a difference. I emailed DiabloSport to find out what was different and all I got was a generic 'improved performance' reply.

There is no difference in the power gains, just the options, for example, when I first got mine, I could not turn off the rear 02 sensors, it wasnt even an option but now it is available with the new revision....

Cool.

Thanks for the reminder, I need to do that tonight.

What rev did you have before r50c? I had r50b before r50c and I could have sworn I had the OBD options.

I’ve had the options to turn O2 sensors off since r42something. Been updating my predator with new revisions all the way as they’ve come available but didn’t notice any new options with r50c.

I downloaded r50b the day it was available and played with the timing advance until r50c was available and I had the timing advanced quite a bit in both rpm ranges. Actually, I was considering uploading the changes I made with the timing as a custom tune to my PC and then download the tune back into the predator for more timing adjustment. However, since putting r50c in the car I haven’t touched the timing yet, car feels nice and strong with no adjustments so far. It does smell a little richer to me though. I’d really like to get it on a dyno and check the A/F.

Any other reports/feedback on the r50c?

I updated mine and it got rid of an idling problem i had. It would go into open loop mode after sitting for a while.. it was idling too lean and then going full rich to account for that... idles fine now so far.
