Rtek 2.0 Tuning
 

Hey guys, its been a long time since i posted. but i've got my new motor installed and running Large Street ported :D :D


so my question has anyone used a Rtek 2.0 to tune with?? i've got one and i wanna hold someones hand and bounce idea's before i start changing Timing and Fuel.

Thanks alot guys!

I have an RTek 2.1 (the new version that fixed some issues I had with 2.0) for an NA motor. It's not that bad, but I'm looking to upgrade here in the coming months.

Did you do any real tuning with it? or did you just install it?

I've tuned it to use my turbo (remember, it's an NA)... I don't suggest it, but I've altered the fuel curve, haven't touched the timing, which is probably why I have an issue with spark break up around 3000RPM, but i'm going to full stand alone for some much needed features.

What are you attempting to do?

I've just finished breakin in my 6 Port Motor N/A and wanna SAFELY squeeze some power out. i just want to know basic's of where i should move timing, and when and how to play the Leading/Trailing Dance. Fuel i can Watch with a NB (WB Later) for now.

Honestly I could tell you some numbers, but there's really no need for a few reasons:

You can not tune fuel with a NB. It can only tell you if you're off stoich (rich or lean), but can't tell you how much. IE usually making peak power at a 12:1 AFR (or 0.8 Lambda). Consequently the timing is more sensitive to what type of gas you're using. If you're using regular (as stated by the Owners manual) stock firing is fine--can verify by strapping it to a dyno and going from there. If you want to adjust timing, you'll need to put it on a dyno (don't go by feel), and slowly adjust it from there. Depending on your spark energy you should see some decent gains (don't forget to go to a higher octane rating when you adjust it).

I understand all that. but, Being as i have a Large Street Ported Motor, Factory timing isn't correct anymore right?

Eh, it's not going to hurt anything. (I'm currently on a large street port)

^Some reading to give you an idea.

Awesome thank you :D

Just a little adjustment/caviot: Timing is not my issue; fuel is. The NA RTek can not tune for positive pressure (anything greater than 5 psi), as such fuel gets dumped into the engine down to 9-10:1 AFR at 3000RPM (when I'd actually begin to see positive pressure at partial throttle).
