I have a 94 JDM GSR in my civic with a P72 ECU... no codes, no power loss, I think I have vtec but not sure lol and I cant rev past 7000 Ive read about GSRs they redline at 8200 top hp at like 7600 i cant make it past 7000

When I had a bad spark plug after I first did the swap it redlined occasionally over 8000 but had power loss now but i replaced the plugs and everything else seems ot be fine just it wont go past 7

Any Suggestions?

 

Check your oil.

 

I change it regularly although it does seem to be burning some

 

Well if you're not sure if you have VTEC, why don't you at least check the engine code on the block.

 

on the block? you mean the numbers B18C1 those are definately there, and my ECU isnt throwing any codes

 

What should I install to get rid of my Revlimit

I also wanna get a Vtec controller of some sort so i can set my Vtec point before the secondaries kick in because with my old 1.6 motor Vtec was noticable I heard a hissing sound but with DOHC the secondaries are too loud I cant hear if I have vtec at all

 

oh so you popped the b18c into your ls?

 

is your vtec solenoid fried?

try taking the lid off the top of your airbox. you should be able to hear the engagement when the secondaries open @ 6K rpms.

Umm B18C would be stamped if it was jdm...you have a usdm one.

My secondaries kick in at 4400 and vtec kicks in at 5600 i got it checked today and my mistake it does only say B18C on the block i checked that as well it must be my ECU maybe its USDM would that cause me to revlimit at 7k

 

i think he just said he had a jdm c1 just to be cool...... it really seems to me that this guy doesn't even have a clue about hwat hes talking about

 

i guess not captain obvious not much about ECUs anyway

its the other way around. 4400 vtec kick in. 5600 secondaries open up

 

oh ok my mistake

 

Maybe you have a LS ECU. Rev limit is around 7K.

 

is there a way of telling besides the sticker on the side panel of the ECU because that could have been stuck on there or something

 

i always though if u had a ls ecu on a vtec motor that it wouldn't even run........?

 

yeah or if i did run with an ls ecu i wouldnt have vtec at all would i

 

Thats true too, you can always modify it and manually control the vtec

 

See if you can switch out ECUs with one of your GSR car buds, or something like that. I assume you have a couple hanging around. Just give er a try to see if your ECU is messed up.

 

your vtec would not run if you have an ls ecu. i still don't understand why you can't tell if you have vtec or not, you should be able to hear it and feel a decent pull. if you have a jdm b18c which you claim, vtec should kick in at 5100 rpms, stock anyways. My guess is either you have no clue what your looking for and/or you need a new ecu. Just my .02 though.

 

pointless response right here...

when i read the thread topic i thought it was going be a joke and the body of the thread say, because i have a B18A/B or something like that haha the end of useless ranting

 

cold rev limit.

check your thermostat signal to your ecu. not the one that runs to your console, but the one that tells your ecu that your engine is warm.

 

Dude no offense, but just reading this entire thread, it makes you look like you dont know what your talking about a major dumb*ss. Please, dont work on your car if you dont know what your doing.
