I was browsing around on JR's website looking for some info on ridding myself of detonation. I was reading the revised '96-'99 Civic instructions and comparing them to my year old instructions to see if there was anything I might have missed. Well, at the end of the instructions are tips. Some of these tips contradict what is said in the FAQ. One of the tips says something that might explain why the boost corresponds with the RPM's (3psi@3k, 4psi@4k, etc.). There's a couple of other tips that talk about preventing detonation. I considered a 160 degree themostat before but they recommend a 180. I talked to Keith today about my detonation problems and asked him about the 160 thermostat idea. He recommended that a 175 or 170 should be the lowest one used. He said a cooler one would make the engine run too rich. I also asked him about adjusting the stop screw on the bypass. I figured that I could maybe see 6 psi at the advertised 3.5k rpm's instead of at redline. He pretty much yelled at me for just thinking about it. In other words, don't mess with the bypass. Keep in mind, these tips are listed in the Civic instructions and not in the Integra instructions. I don't see why these tips couldn't apply to all of our cars.

I think I might give a 170 or 175 thermostat a try. I looked into an oil cooler but they're kind of expensive. Where did you get your oil cooler from and how much was it?

Detonation solution = ZDYNE SECU.

Yeah, the Zdyne ECU would be nice if they had one right now for our late model cars. For the time being I'm going to have to find other ways to rid myself of detonation.

I had that oil cooler laying around for years intended for another car. I think it is a Hayden. (good for over 400 horsepower.)
There isn't much space to mount in the engine compartment, so I had to run hoses all the way up to the front of the car. It now takes about five quarts of oil. I also have to use a different oil filter since the adapter fittings that came with the kit did not fit the Integra oil filter thread. Now I have to put on an oil filter for a Chevy Silverado http://www.hostboard.com/ubb/smile.gif
Everything works fine though.

Dude,
I'm running a 160 F thermostat and yes it does run richer. I was getting detonation on the highway at speed, but not down in the lower gears.- that was from running too lean on the fuel pressure regulator (40 PSIG)
I dialed in the JR pressure regulator to 60 PSIG (at the fuel filter) and all detonation is gone. ( 8 BTDC with stock fuel pump) But now when the engine is cold it bogs because it is running too rich @ idle, so I'm going to go down to 55 PSI.
Another thing which may be giving me shit mileage is the jumbo oil cooler I have in front of the radiator. Although my temp gauge stays in the middle, I think it is running too cool with the oil cooler, synthetic oil, 160 F thermostat (although the oil cooler has a thermostat)
With that said, I'm going to put the 195 F thermostat back in. I wish they were easier to swap out, 'cause then I would put the 160 F in the summer and the 195 F in the winter.
Soon I should have the air/fuel meter installed and can give more accurate analysis.

Waveoff, the set screw on the bypass has nothing to do with getting boost any sooner because the screw just limits the bypass valve's travel from overshooting the normally closed position. If you mess with the set screw, the bypass valve may never be at the fully closed condition causing your boost to leak.
-
Well, my whole reasoning behind the screw thing was that I thought that maybe my screw was set so that the bypass wasn't closing all the way when I mash the pedal in. But, after Keith's reaction to my idea I don't think I'll be messing with it. If I do, it'll be in very, very small increments.

Just make sure you put some threadlocking compound after you adjust it. Speaking from personal experience, those damn things vibrate off like crazy. Good luck.
-
Good idea...I'll be sure to do that.
Well everybody, I'm leaving for about a month tomorrow. I won't be able to play with my car for awhile. It's been fun hanging out here learning stuff with you guys and sharing experiences. You all have been a real cool bunch to me even though I drive a Civic. Talk to you all when I get back.

I forgot to post the link to the tips. Just in case some of you can't find it click here http://www.jacksonracing.com/instructions/989-200.pdf .
