You should get the main screen page by just plugging in the unit to power even without the serial cable hooked up. Page will show Pred version # and 4 options. Is the power unit 9V /600mA minimum?

thanks the power suply has 12v 150mA on it is this ok?

Yes, that is good power. I think you will have to wait for the Diablosport team to chime in with any other possibilities to try. Sounds like an issue with the handheld but wait for them to verify.

My suggestion would be to drive for a week and feel the results, sometime they take a liitle while to appreciate. Note the shift and power curves to try an determine if you want to change anything. Do some logs to see if you have an issue with knock at accel anytime or WOT. You may make your adjustments when you want or just leave all alone. How much did you have to adjust the slope? Let's face it the Predator will only give you so much extra power and better drivabilty but it will not change the world around with a tune. Enjoy and work at the changes methodicly.

thanks again for the input i changed the injector by -6 how or when will i know to change the timming or can i log this and let data viewer suggest an adjustment? i plan on a k&n cold air intake in the near futre also magnaflow cat back will these help?
GO SAINTS!

Dataviewer will not suggest LTFT's that is DSReg for that. Are you using the Diablo tune? Timing is liimited to good fuel availability If you are going to change to CAI and Cat back soon I would wait until they are installed. Also, I would suggest to investigate the CAI and cat back you want to install only because there are good systems and better sytems available. Do some homework and you may be pleasantly surprsied. Nothing against the products mentioned but... look around. I use a Tru-flow and Gibson myself and am happy with them but to each his own, and there are more vendors/products with new stuff now than before. Drop 06MonteSS a line to get closer to what you want as far as honing in on the tune..... And the Saints did it
