Vtec point?

[mikecrx1990]

Ok everyone, I just got my JDM D15B in my 1990 crx. I left the car as OBD-0 and I have a jun chip in my PM6, for a 8200 rev limit ( I never go that high) and more agreesive fuel. I also have a I/H/E and the buddy club vtec controller. What is stock cross over and should I change it? Thanks guys.

i doubt thats a real jun chip and chances are your just getting shit load of fuel dumped in the motor convert to obd1 and get a real chip and tune you'll see better gains and just wire in the vtec i'd set it for 5k on the vcon

No its a real jun chip its a soket not a soder job I even looked up the part number. Also as for fuel it only dumps at higher rpm I asume cause you smell it then and if I check the plugs after alot of high rpm runs they are a little black but if I drive around a bit normally they go back to their chocolat brown color, so I think the chip is doing what it is supose to do. I am going to do the obd-0 to obd-1 swap but got to save a bit of money first. This is just a temp thing. Thank you though.

If your ecu is chipped, get some free tuning program and tune it properly yourself. Invest in a wideband a call it a day.

If I set the vtec point to 4500 or higher with apexi VAFC there is almost no difference in performance, If I set it at 4000 or 3800 I don't have any more the power loss when I change gears.
