So, i'm having problems with ecu decisions, I'm hearing lots of mixed opinions on whether or not a p30 ecu will work nicely with my stock ls/vtec build. Any Guidance would be greatly appreciated.

 

chipped p28 is the best...you can make a tune for your own motor...can always convert to hondata later

 

i understand that, and i have a virgin p28 right now, but i want to want to use it for when i go turbo. i dont want to tune as little as possible. so basically would a p30 ecu work for the time being?

 

dayme...its you...you started another post and i didnt notice...well...people said it would work but i wouldnt...just for the fact that p30 is for a 1.6 and you are runing a high compression 1.8. but thats me...i cant afford to blow **** up anymore.

 

what do u mean, dayme its me? i only have a little over 100 posts...anyways they're only pr4 pistons its not going to be high compression.

my bad dude...i still wouldnt do it. but its safer than the other guys i guess

 

no thats not me, and i saw that thread earlier, and thats what really got me thinking infact. i know my pr4's are significantly lower comp. than p30's which is why i was wondering. does anybody know what kind of compression ill be running with my pr4's?

 

damn, i found a calculator, and it said about 10.3:1, thats pretty high, but the p30 is almost the exact same comp. ratio, in fact a little higher, so shouldn't i be ok?

 

cant really tell you man...honda didnt make a p30 for lsvtec

 

lol no joke, they never made an ecu for ls/vtec. i think it'll be ok for as mild of a build as it is, and if worst comes to worst I'll use my vafc-II for a little while to help out the p30 if it really needs some advanced fuel maps.
