Went to DSR for Dyno Tuning............

[MartyMarGSR]

since you dont have a standalone, what mods do you have that allowed you to tune your fuel delivery etc.

what changes did they make from the basic untuned JR setup using the FMU the way it came in the box and bolted in?

Right now im running a walbro 342 and the JR fmu, pushing ridiculously high idle pressure, with timing set back at 7 degrees on 92 octane gas.
Im also running NGKBKR7E's, gapped at about .035-.036

I have never really heard any detonation since i put in those colder plugs (for the first 3000 miles i used my stock plugs with stock gap still), and the car had pulled way harder, but the plugs were showing signs of running lean since they were completely white on the tips.
And im trying to figure out a few ways to help tune it up w/o a standalone (no money yet)

I'm running NOTHING.
No Standalone
No Band Aids
Nothing
They used the fpr that came with my kit to drop the fp. I'm using the one heat range colder plugs but they are the Platinum?s (BRP) not BRK. And my gap is around 42-45. Pretty big but no detonation present. Also, I'm in Cali so I'm only using 91 Octane. What are your numbers with the set up you have?

I did this for awhile at 8psi. Tuned on a dyno as well. But after about a month and half I hooked up the J&S again (classic not the ultra) and still showed the infamous tip-in detonation on the boost transition. After the map mod, this went away.

Maybe you have zero detonation, but I figured those little bangs add up after awhile (more like the subtle damage of cigarette smoking, rather than breathing chem warfare gas as an analogy) and taking care of it with the map mod would pay some dividends in the long run.

[GS-Raw]

Wow that's a great analogy!
Thanks for the advice. I must say, you definatly gave me somthing to think about. I plan to go Hondata/Jim's pulley soon so hopfully I'll be fine until then.

I haven't been to the dyno yet but I put on my JR map mod and it feel better

Finally, after driving around for the past 12 months with a non tuned JRSC GSR, I finally got my self to make the trip down to Dyno Spot Racing out here in northern California. My over all experience there was great and the guys down there were very knowledgeable. The shop has a 98 JRSC ITR putting out 255 whp and does 12.5 @ 108 mph, all at 8 psi! My results were the following:

BASE: 198whp 138 ft/tq
New plugs: 200whp 140 ft/tq
Tuned: 207.3whp 150.5 ft/tq

I was actually quite amazed that changing my spark plugs gave me 2 hp to the wheels. As soon as I go hondata, I plan to go right back here for some real fine-tuning. I'm very satisfied with the results, I went from 198 whp to 207 in a matter of 50 min.

well the pics don't work so here are the numbers;
base
201.5whp/153.9ft/lbs
final
225.4whp/160ft/lbs

[MartyMarGSR]

hey morepoop4u, do u remember what kind of setting u put on the cam gears when u got it tuned?

[morepoop4u]

its +2 on the exhaust side. i gained 10hp by doing it.
