as the title says, i chipped a p06 and did vtec conversion. the car will go into vtec once and then give a code 21 and wont go into vtec again. any help would be appreciated. thanks.

Re: chipped p06 vtec works once then gives code 21
Are you using the 5151 high side switch or are you using the ISP 7081 high side switch

i will have to check, i have recently taken over a position at a company and am using all the supplies they already had. thanks for the reply. does it make a big difference which high side switch i use?

No it doesn't the ips one you have to cross pins and the probelm you are having sounds like what happens when the pins are touching. So make sure to check the solder jod on IC-14

you cant use a 5050 switch? i have always bought my components in bulk from xenocron and never actually looked into the specifics of them. after looking at the supplies i have almost all of them are 5050.

Yes, 5050's will work once and code out

Re: chipped p06 vtec works once then gives code 21
there was a post on here a while back about how to wire up a 5050 so it works (it's not plug and play like the 5151) but for some reason I can't find it now... I'm tired and the search is not cooperating.

Re: chipped p06 vtec works once then gives code 21
thats for the replies everyone. i read in that thread that someone did it and it didnt work. i have traced my problem down to the 3 prong transistor in Q101 and Q26. the transistor i have are D1423AR99 and the ones that i found to work are D1423AR58. anyone have any insight? i cant find the proper ones i need anywhere.
