Hey guys I some help with the gsr. I took some pics of the brand new plugs after a 5 min drive. Here's the prob, I as long as i keep the car under 5psi my car is fine but as soon as a load is put on it over 5psi under acceleration the car boggs down, sputters and sometimes backfires. This is the second set of plugs I've put in and they have looked the same. Plugs come out looking black, I don't know much about this but I do know its not good. any help would be greatly appreciated.

setup:

Stock GSR engine
LHT Turbo kit
Precision 5031e t3/t4 turbo
walbro fuel pump
Precision 580cc injectors
Hondata s200 p28 w/boost
street tuned @ 8psi

96 GSR-T

They look fouled and/or very dark for fresh plugs, did you gap them correctly or did you just open the box and install them?

Do you have a Wideband?

I gapped them according to the info pulled from ht. .028-.030

no wideband

It is not easy to tune correctly with out a wideband, narrowband O2's just are not responsive enough. Also maybe you should go back to the stock plug, either that or you are dumping way too much fuel or need to increase the timing.

Do you still have the old plugs from the tune? If you do you need to measure what they were at when the car was street tuned, also make sure its the same type of plug. I would try a little tighter than .028" and see if that helps any.

When did it start doing this? Throw a wideband on there. Sounds like the tune is way screwed up or you have some other problem causing incorrect fueling.

The car started doing this almost a month ago. The car is just toy of mine and I don't really drive it at all, though I would like to get it on the road more. I'm new to the western ky area and don't know where to get any dyno tuning, as I am sure this would help resolve my issue. If i can't resolve the issue you guys can look for the car in Honda-tech Market place. I really don't have the time for it anymore....

get a wideband... sounds like a tuning issue. One thing I would do is try another MAP/chip first.

Try using macro mode on your camera next time.

just tried new plugs, distributor cap & rotor, and new chip from phearable.net. Plugs look exactly the same and having same bogging, sputtering probs.

All this and no cel

car wouldn't even start with the chip from phearable.net so I put my old one back in and it idled fine like normal.

FIXED!!!!!!!!!!!!!!!!!!!!!!!!!!

You guys can't laugh at me for this, maybe a noob mistake nevertheless it is done. I had the new program setup to run on a hondata 4 bar map sensor, problem was I never swapped it out with the stock map.
