what ecu could i use for my 97 ek? i have the 2000 gsr ecu but one of the plugs do not fit. Should i cut off the plug on my car and the plug from the donor car and rewire it together? Also, i heard that the car won't start because the gsr ecu has immobilizers. Is it possible to disable the immobilizer? Is it just easier to get another ecu? If so, which ecu? Is it also easier to get an ex harness to run vtec? Would the ex harness fit the p72 gsr ecu?

AHHHH SOOOO MUCH trouble with this swap...already! and i didnt even swap anything yet either.

HELP!!!

the problem youre running into is you have the wrong obd.

youre car is obd2a while the motor and ecu are obd2. the quick and easy solution for this is to piuck up a 99-00 si harness. itll be plug and play with your new motor.

good luck with the swap.

Or you can use a 96-99 GSR ECU to plug and play with your harness.

that too haha

mr 636

ahhhh thanks guys!!

last question...long shot and i know there are HELLA diagrams out there, but does anyone know how to wire the vtec? im looking at the diagrams and get lost everytime. i just bought a 97gsr ecu for 80 bucks...i got ripped off huh?

thanks again guys

the vtech wires up to A8 on the ecu. and the vtec pressure switch wires up to C15

Wannabe JDM

this is a good page for wiring and everything

mr 636

thanks again man, i really appreciate it.

do you know where do you add the wires to? you sed from A8 and C15, but where do you hook those new wires up to? i guess thats why i'm confused.

Wannabe JDM

Vtec Pressure switch C15
Vtec solenoid A8
Knock sensor D6
IAB solenoid (B18c) A26

the pressure switch and solenoid areon the front left side of the valve cover and the knock sensor is on the back of the block under the intake manifold. im not sure about the IAB because that is only on the gsr.

now the tricky part is if you ahve a jdm motor you will not have a vtec pressure switch or crank flucuation sensor.

this also saved my sanity many times and online version of the helms manual:

holy crap...someone took pictures of the whole book? madddd props to him for sharing. and again thanks slowej..you are soooooo helpful...wooo!! looks like i get to continue with my swap tomorrow afterall!!

Wannabe JDM

no prob

im in the middle of my swap so its all fresh in my head

mr 636

could someone tell me what mounts to use? should i use motor mount inserts?

Wannabe JDM

read that page i gave you above.

or you can just pick up a nice set of hasports.
but you still need the rear tranny, and the si upper tranny bracket. adn the gsr front lower tranny bracket.

mr 636

omg...2 days of frustration...its in...but the stupid radiator dont fit!!! FAWK! the hoses from the gsr are too big for the d16 one and the d16 hoses dont bend right. the stupid dx harness is all bent outta shape....my buddy lengthened just about every pllug. we converted like 4 plugs...i hope thats right...welp going back down to try and start it sooooooooooon. NO FUEL HOSE!!!! DAMN IT!!! my **** is like 2 inch short and my bike is stuck between the garage and the car...no ride 2m to work!!!

JeffBro

Dude all you gotta do with the radiator hoses is use a screw hose clamp and clamp it down alot and it will work. If it leaks you might just need new hoses. I dunno about the dx harness but with the one on my 96 ex all I had to extend was the vtec wire, O2 sensor, and the IAT sensor. I used a 96 p72 ecu and it pluged right in. Though now Im prob gonna switch to a chipped p28 soon. Also I put a skunk2 manifold on so I didnt have to wire up the secondaries.

BTW: If you want to make your fuel line work all you gotta do is bend it a little and/or flip it around and you gotta take that wierd metal piece off that prevents you from putting it on the opposite way. any questions let me know...

mr 636

thanks man...ok i got the car running and all...open header!! CEL is on...b/c of the secondary o2 sensor is missing. ok...it's a shitass job for wiring, but it seems to work fine right now. also, how do you make the throttle work? i just put hella spacers to give it enoguh slack, but not enough to get a full throttle pedal....not like i need it. but there's a lot of slack left. do you kno why is the rev limiter at 7thousand? i'm running a 97 gsr ecu on a 2000 gsr motor.

mr 636

would anyone mind posting a pick of their obd2 gsr'ed motors? my **** looks soooooo ghettofied

slopoke27

gluck with everything man...i'll be in ur shoes really soon...but im stickin with obd2 haha

mr 636

ahhh im sticking with obd2....!! all my buddies say that going obd1 is the best for p28...but i want to be smog legal!

mr 636

does anyone know why my 00 gsr with 97 gsr ecu is bouncing off rev limiter at 7?

does anyone know what correct thottle cable i should use? the dx one is tooooooo long.

does anyone know where to get ecu pins? how much does it cost to just have someone wire vtec?

B20Vtech_EK9

i have the p28 , chipped on my gsr swap and it runs hard

mr 636

ok...

bump

Wannabe JDM

waht i did is i found a junk harness in a junk yard, one that was for the most part destroyed, and used wires and ecu pins off of that. all i did was pull one of the plugs out of the ecu and splice a wire to the vtec solenoid to that.

vtec is just a single wire. do you have the motors origional wring harness?

Wannabe JDM

if you didnt live in cali i would give you a hand with the swap. unless you wanna pay me to come out haha.

mr 636

lol thanks man. i hope radioshack has these things. i'll go later or something. i still have no idea why it bounces off rev limiter at 7k. do you kno if a LS cat would fit on the gsr header?
