i have a 00 gsr. looking to get an ITR ecu, and cams. then get an 4-1 exhaust, maybe 2.5 inch collector and the JG edelbrock intake manifold. n e body know if it worth it? what i should and shouldnt do? what year ITR ecu should i use? whats this immobilizer thing in the ecu? thanx for your help

 

The ITR ecu won't be able to run the variable intake so you would have to change that too. You would be advised to also upgrade the valve springs to avoid valve float. I don't know what year ecu would be the best choice. The immobilizer is a code that has to match between the key and ecu for the car to run. A dealer has to re-code it for you. They will want proof of legal ownership of anything you bring them.

Oops, didn't notice the part about the JG manifold. From what I have seen/read, that manifold looses bottom end and midrange. I think it needs either more displacement or higher revs than you can get without building the bottom end.

Use a '00 or '01 USDM Integra Type R ECU. The immobilizer is an interrupt in the fuel pump main relay.

From the dyno's of the JG Edelbrock manifold that I've seen, it lost varying amounts of torque and whp in parts of the powerband. Until a combination that works with that manifold becomes public knowledge, I'd recommend the Skunk2 intake manifold over the JG.

 

i have the skunk2 mani and im really pleased with it, although i need some cams and valvetrain to compliment it. you could also just run a jumper harness so you can run a chipped out ECU, which has to be a obd1 ecu of course. also a chipped out program usually doesnt enable the IAB's so you should change out the mani to one thats a type-r style such as the skunk2, good luck

 

i dont know what to believe n e more.
i was told that the type R ecu, no matter what year, would work perfectly. and that the JG was a great design over the overpriced skunk 2. plz help

Get the skunk2 manifold, the JG is built for either Forced induction or an engine that is going to be ran well over 8k

 

alright, i guess the skunk 2 would be better
now for the ecu?? someone up top said that i should get the 00-01 ecu cuz of the imobilizer is in the fuel pump something like that. can someone explain this. will i need to reprogram my car, or the keys, if i put in an itr ecu???

 

plz help.

 

all itr ecu are the same

 

if i would be you, ill put a obd1 ecu in there

 

All ITR ECU's are the same. Just buy a P28 and chip it

 

how about chippin my ecu? would i need to configure the keys with the new itr computer?

 

you could buy hondata for the p28 and keep the gsr manifold with IAB control with p72's.


def dont do a jg manifold though. either a skunk or a aebs. the aebs is suposedly very good.

 

whats IAB???

 

n e body know what iab is?????????

 

ok..

ALL ITR ecu's are not physically the same. Program wise, yes they are...but not physically. There's 2 types of ITR ecu's OBD2a (96-98) & OBD2b(99-01). You need the OBD2b version since you own a 2000 Integra, which is OBD2b wire/ecu equipped.

Since, you own a 2000 GSR, you need to stick with a 99-01/OBD2b ecu. There were no ITR's made in the US in 99, so find yourself a 00-01 US ITR ecu. Then you'll need to have the immobilzer (IMM for short) removed from it (hit me up, I can remove it for you for a certain $$). Now, if you don't remove the IMM, then your car will not start at all because of the IMM not being removed (its a theft deterrant device from the factory).

Once you have the ecu thing squared away it will run best once you apply a Skunk2 manifold to your car.

The IAB is actually a sensor that the ecu talks to in order to control the activation of the dual butterflies. The dual butterflies help create better low-end torque.

Here's a picture of a dissasembled GSR IM:


Here's a picture of the IAB solenoid:


Your current GSR ecu controls the opening/closing of those butterflies through the IAB sensor as stated above. Once you put a type-R ecu in your car, those butterflies will stay open all the time, which is slightly shitty because you'll lose some low-end torque....but its really not that much of a loss in power. Once you apply the Skunk2 I.M. to your engine, you don't have to worry about the IAB's at all, since the Skunk2 IM totally eliminates the use of the IAB (it doesn't have dual butterflies inside of it).

Type-R cams are a good start too.

 

thanx for your help, that was perfect. very last quesion, and that will be it. the dealer tells me that the immobilizer is not in the ecu, so it wont matter?? who should i believe???? thanx

The immobilzer system has 2 parts, the actual immobilizer chip inside the ecu and the ignition (key-hole).

There's a chip inside the ecu that gets a response whenever the key is inserted into the key-hole. The chip has a code on it that recognizes the key being inserted into the keyhole. When that key isn't the key that came with the car/doesn't match up, a red flag goes on in the ecu and it goes into its immobilizer mode disabling the car from starting. It mainly cuts the fuel pump from working, and I think something else too. That's the jist of it though.

So for instance, if you take your 00 GSR ecu and let your pretend-friend who owns an 00 GSR as well, borrow your ecu, his car will not start at all because the IMM will not recognize his ignition/key system (it has to recognize your ignition system + key), therefore disabling his car from turning over/running (with your ecu). But, if you get the IMM removed from your ecu, it will run in his car, just like removing an IMM from a 00-01 ITR ecu will run in your 00 GSR.

BTW, all 99-01 integra's have an IMM, 99-00 civic's do not have an IMM.

PS: I don't think it would be a good idea to bring this info up to a person working at Honda. They might think your a car theif. Reason I know about this is because I'm into ecu reprogramming (chipping). see sig.

 

thanx for your help katman
