hey i have done a b16a swap into my 98 civic, i put in a jumper to go from obd2a to obd1 so i can run the p28. the p28 is chiped with vtec kicking in at 4400rpm and rev limiter at 10,000rpm . we are expirence a problem with reving it to the rev limiter. when sitting parked at idle i rev up to see if it will bounce of the rev limit of 10,000 rpm but it will only go to 4400rpms. i have tried swaping ecu's to see it my ecu or chip program was bad but they all did the same. it seems though on all the ecus i tried it would rev limit right were the vtec would kick in on all the ecus instead of at the stock rev limit. can any one send me in the right direction to figure this problem out. it used to go all the way up to rev limit but now it wont. all help or comments would be appricated thanks

Have you checked your VTEC solenoid? does it rev up all the way when the cars moving and in gear?

yes, the vtec will in gauge once moving and run all the way up to the rev limit. I thought maybe it was some thing to do with the speed sensor. i know vtec wont ingauge unless speed is read. but that still shouldnt stop it from reving up all the way when not moving. i thought the vtec just wont ingage. it use to rev up so i could lunch from the line now i cant.

Well first off, 10k RPMs is really hurting your engine

second, your gonna need an aftermarket ignition meaning an MSD box, that controls where your limit is set, thats how you adjust the rev limit

crasyj

well just to let everyone who has looked at this thread i have fixed the problem of the rev limiting . it turns out that the fuel rely had a short in it. i dont understand why it was affecting my motor when i was reving it up but it is fixed. so the next time someone might have these problems check your fuel rely.

10k rpms

thats 10 thousand revolutions per minute, thats fucking fast as hell, the engine wasnt designed to handle that much which is gonna cause some serious damage

JEV

lol, piston damage or connecting rod damage....even cylinder wall damage.

well, he probably knows what he's doing.

well hey 10k rpms my be high but i have going to 9600 rpms a bunch of times and had no problem. the other thign is i don't usually go that high. i have a b16 with a p28 ecu. that means rev limit at 7200 rpms a stock jdm b16 revs at 8200 rpms. so thats the whole reason i have chiped the ecu. i didn't choose 10000 rpm to rev that high i just wanted to be able to go back up to the stock 8200 rpms. hey and another thing if you knew anything about a honda witch is nothing like a mustange youd know that an s300 is used when doing big projects which allows to set the rev limit. so sorry but u don't have to buy the msd 6a ign. to set your rev limit . u can purchase an msd 6a ign that does not have rev control and there is a reason for this. thanks for all ur comments

JEV

your welcomed. plus hondas are reliable,lol.

lol, hmm, now where did i read this.

well, 75% is the factory all out tuning, method,lol.

so there's still 25% untouched,lol.

but yeah, i still no know much on this stuff so, i can't really say.

10k rpm, is probably the highest i would go, any higher, and you'd have to be getting expensive parts.

i'm forgetting something, which would explain this...the 10k possible, but like i said i forgot,lol.
hmmm, would it be camshaft....naw. any guess to what can help support this type of rpm.
