Hey, fellas what's up. Quick ? On the 1gen B16 I know Vtec kicks in at 4.5. When does the second one kick in? Just curoius. My orig. ecu was a automatic B16 so redline was a sorry 7600. The shop who did swap sent a ecu out to have a spoon program ecu done. My vtec engage at 4800. The redline is 9 but I don't take it pass 8200 sin ce bottom is stock. Don't want to do damage. I have basic bolt ons so can't really tell when second vtec kick in like my Gsr.
Would the only easy way to be is have it dynoed. Thanks for any imput.
