i'm thinking of getting a CTR ecu for my car. I have a stock JDM ITR motor all wired up and running obd-II. i am currently running a chipped P30.

any benifits of running the CTR ecu? i know the redline is about 8200 where the ITR redline is 8000. would i have any problems?

TIA

 

not a big enough fuel and ignition curve for the .2l of displacment the ITR has. i wouldn't do it.

never though of that

any more suggestions?
would it work better than a 00 Si ecu? i've ran it with that and its alright

I am surprised that your si ecu worked, i have the exact same swap and when we first used my si ecu vtec wouldnt even engage. Just use the P73 that should have come with it. Thats was i use and all works very very well.

 

yeah the Si ecu worked/works fine. where i got my motor from they couldnt find the p73 with the motor so they gave me a obd-IIa which have different plugs than mine. at the time i figured that i was going to run a obd-1 ecu so i wouldnt need the p73 and i sold it.

the peak power of the motors isnt controled by its ecu, and both has same fuel cuts,
i lent my pct ecu to one of the benen guys for the super tuner battle, and he didnt seem to have any problem with it. the ecu's are almost identical, but i couldnt imagine any true benefits of switching to a ctr.

that comment makes no sense at all.. This is false, I have owned and ran a JDM ITR motor on a SI ECU for over 2 years. Not anly that, dynoed, tuned and it ran fine with proper curve in fuel and power. If you want a differnt change over and fuel cutoff than yeah, change it up.. I would run it over your P30... Talk from experience not guestimating....

different vtec solenoids. single plug on the itr vs two plugs on the 00 si. should throw a check engine light.

 

USDM 99-00 SI ECU = OBDIIB
USDM 96-98= OBDIIA
JDM P30 = OBD1
JDM 96-98 P73 = OBD1/OBDIIA plugs

I would never run an SI ECU over the P30 obd1. I guess it won't matter much if you have a engine management computer. Just stick with the P73 if you OBDIIA. If your not then go with the P30 or even P28 chipped.

would run the Si ecu over the P30 or the CTR ecu?

i swapped my Si solenoid over to the ITR

i'm running a JDM P30 chipped. what about JDM 99-00? OBD-IIB plugs?

 

I'm running the CTR ECU, seems to be working great, I did notice that it idles different from the SI ECU, and the fact that it takes a half second longer to start up.

 

I have done a B18C JDm swap I used the OBS II Ecus that came with the car. The Vtec has stopped engaging and there is a Code 5 CEL the CEL was always there any help suggestions, Please

 

get a p73 ecu if u dont already have one a pct ctr ecu wont do much or anything
for u remember a ctr is a destroked itr!!!

why doesn't it make sense? the ITR motor has more displament and other aspects of the CTR are different from the ITR. i didn't say it wouldn't work i just said i wouldn't do it.
