Chipping a P28 for D15B Vtec
 

Hey guys,

I had a spare P28 ecu with me for sometime now along with the original P08. My car is NA, with some bolt-ons like I/H/E, no internals or anything serious. So I just sent the P28 to a guy to get it chipped. So is there any specific things, like Vtec crossover point or rev limit ...etc, I should tell the guy to get optimal and safe result with this?

advanced thanks!

The only advantage in your situation is launch control

I dont see any other reason

Just curious, how could it affect launch control? Anyway right now there is a problem with launches on my car, like the car doesnt have much power at launch, specially at 1k to 3k RPMs. Mid and hi ranges are fine. And idles very low. So at times i have to keep revving for the car to not to stop in traffic and while going uphill
