Car is a 94 gsr has a b18c bottom end itr head with a t3/t4 57 trim on ten pounds and 440 injectors and it has a b16 hydro tranny. I'm trying to tune the p72 and was having trouble with the p72 base on crome... Car wouldn't go past 6500 and VTEC would not engage... I read yeasterday that crome works best on the p30 base and thats the only one that the special features will work on. So this morning i started with a p30 map and spliced in the p72 fuel and spark tables for the high and low cam setting and added the boost tables i have not had a chance to get back to the shop to burn the chip and try this yet cause im at work till tonight. But i wanted to post up and see if anybody has heard the same thing about the p30 base and if this map sounds like it will work any help would be great im buying pro next month since i couldn't fit it into my budget this month so then i can realtime it and do it better but i would like to get it some what close like this

 

p72 & p30 base code work just fine.
I doubt the issue had anything to do with the p72 base code being used.

 

Ok so any idea as to why we are having this problem even after we set the rev limiter and the rolling rev it still stopped at 6500 for the hell of it i even went with what is suppose to be a stock b18c map that crome has pre loaded on there and it still did the same thing no VTEC and 6500 limit...

 

Are you throwing any codes? Anything that would keep it from engaging vtec?

 

Nope checked that first no cel and no code

 

Before buying cromePRO id strongly suggest looking into www.ectune.com

 

post your bin file.

 

I'm actually reading a thread on ectune right now i need to contact them to see if i can get the tunner package burning chips is so much easier imho plus the fact that my honda collection stands at five and goes up or down often... Im at work right now i will post both my problem bin and the one i worked on today just don't flame me to much im new at this just trying to learn more about the cars and motors i love

 

Fyi i won't be off till 9 pm your time prolly have it up before 10

 

ok so everytime I try to post an attachment my pc locks up pm me and I'll email them to you or I'll post them up tomorrow from a different pc sorry. thanks for the help either way

 

ok the first one (24th) is the bin we were using it won't engage vtec I actually think this is a LS map not sure I never messed with it got it off of xeoncrome I think the second one (25th) is the one we tried to get to work its suppose to be just a B18C map with more fuel but it cuts at 6500 and will not engage vtec either.... the last one is one I worked on yeasterday its prolly not right either but I'm not sure what i'm doing wrong... as far as the rev and the vtec is concerned. fuel maps might be screwy I know but I have not got the wide band on the car so we can get it closer. Like I said don't bash me to bad I'm new to this all I've ever tuned before is my bikes PCUSBIII with an old LM-1. and thanks agian for any help...



(in case someone did not read this whole post and just blindley copys one of these bin I'm saying now its not my fault if you mess up your motor these bins are not good and ar not complet so don't blame me because you don't pay attention.)
