hey all, I tried my gsr ecu in my car today(94 2 door accord ex with swapped jdm h22) and when vtec engages with the gsr ecu which is at 4500 rpm it bogs down for a second then comes out of it. I was running a jdm p13 ecu but i wanted to rty this ecu because of the quicker vtec engagement. I was also told it will build more power than the p13. Now it also throws a code for the knock sensor which is hard wired due to the swap. I know that the pins are in the same spots as far as the ecu's go (d3 for both) so why is it now throwing a code and not with the p13 ecu? another thing is i think the gsr ecu feeds more fuel than the p13 because it smelt rich when i first started it on the gsr ecu. it did feel as though the car went quite a bit better and I have heard of people runnin the, what is it p72 gsr ecu with the h22 so i would like to be able to get it to come out of this bog and get it to stop throwing a code any advice is appreciated thanx
