if you have a bad lead/heavy foot your gas mileage will go down with the tune just a warning!

 

Thanks for the feedback. Personally, the fact you don't need to remove and send your current ECU is awesome! What great technology form RR Racing.....

 

the process is simple and painless. VERY HIGHLY recommend you connect a battery charger during flash . Battery drains super quick. (Rr recommends this from the get go, I believe them now that I've done it. I'm glad I followed the advice)

 

Just out of interest, why would the battery drain quickly? The capacity of a car battery is enormous...

(I can understand why you'd not want the battery to go flat during the re-flash)

How long does it take?

 

not to long , it's all about being safe and not having the car die midflasf. I watched the voltmeter visually move down. You can't kill the nav system and is was at night so I had the interior lights on but that's about it. I had a starting malfunction while back , the engine immobilizer was tripping when I reinstalled my stock ECU . It was easily reset using the OBDII jumper technique but the car batt was extremely weak afterwards.

Before this I had made four start attempts the battery wouldn't crank anymore so, I had to fully charge it and leave it on during the obd reset.

 

Theres an option to cut the screen off.
