about to test out a si ecu in my gsr just for the hell of it this week......is it gonna run any worse?

1.6 and 1.8 hmmm

any comments guys?

Assuming both computers are the same OBD designation, do you have a different intake manifold? How are you going to open the secondarys?

gtowni3

i have a stock im bro

rodrez.

Your ECU helps activate the secondarys in your intake manifold. If they don't open, you're going to lose quite a bit of power on the top end. You'd have to rig it to open up.

make sure your model gsr is obd2b

gtowni3

yup its obd2 gsr...i took off the line on the secondary butterfly

I had a p72 (obd1gsr) in my hatch for my ls/vtec and swapped it for a p30 (obd1b16) i drove it for 5 minutes and decided on my way home i was gonna stop at the atm and get some money to offer this kid for his ecu. Car Def Pulls harder.

i had a gsr ecu in my type r hatch for a little while and the car got me around but did not perform anywhere near 100%

incorrect. the secondaries are open by default. the ecu triggers vacuum to the secondaries and then releases it at the set rpm...

I've run a si ecu on a gsr for quite some time with no ill effects, vtec is more prominent when it kicks (higher revs) didn't notice anything as far as actual performance...

btw, unless you switched to a different IM or removed the butterflies completely, you're only hurting yourself through loss of torque

ahhhhhhhh too bad .....ecu doesnt fit cuz its obd2b and i have obd2a harness.....DAMN!!!..........but i am getting rid of it itr ecu 2moro and putting a stock gsr obd2a ecu, since my motor is bone stock besides intake, fuel pump lol.........skunk2 im is being put on this friday


any comments if the car will perform better with the gsr ecu??

gracias
