I talked to my local hondata tuner today about the s100 unit and he said that the hondata+all the other necessary equipment, will cost me about 1000 CAD which comes to around 700 USD...he said that he would road tune my car and it would cost an additional 400 CAD (260 USD)...he said that the road tuning would make my car run very smooth

however, he doesn't have access to a dyno and i would have to basically dyno tune it myself

I will be putting in jun3 cams, cam gears, spoon headgasket + I/H/E

my question: is road tuning necessary (would the car run decently smooth without the road tuning) and are the prices he quoted me fair?? Should I look to another hondata dealer (ie C-speedracing which is several hours away from me)

Any help would be greatly appreciated

I would personally go somewhere that had dyno access and experience.

i would do that better than just on the dyno machine if i have money.

but "necessary"?? not necessary, i believe 90% ppl here tuned it on dyno, at least i'm one of them, and graph tells u how your car runs.

if i only tune at the dyno, would i still get good results for everyday drivability?

Wayne tunes with a wideband 02 sensor in the header - and tunes for the majority of the fuel curve to be close to stoichiometric. Road tuning also more closely approximates the actual conditions your car will be running on (i.e. fresh air to the intake, full/partial throttle etc).

You must get the road tuning done OR dyno tuning (or both).

If you see Crescent - he will do the road tuning part as well - unless you are willing to drive your car to ISA to get it dyno tuned.

My car runs great after the road tuning by Garage Five.

Is Garage 5 still around? I went there a while ago and the shop was closed down. Have they moved?

yep they moved.. http://www.garagefive.net

Stoich isn't always necessarily where the most power can be found though.

I always think that street tune is more important than dyno tune for Hondata, since you can tune the partial throttle on the street (which I would say you are using 90% of the time), and can only tune for full throttle on the dyno!!

Type-Rare#1248

Thanks for everyone's input

I think I would do both

Big Phat R, how long did it take you to tune on the dyno as well? were the gains worth it?

Dropspeed

When we tune a Hondata system we always install the wideband O2 and "street-tune" first before we put the car on the Dyno. After Dyno tuning is complete we drive the vehicle on the street with the wideband still connected just to verify.

I've had about 8 hours of street tuning. I messed with the fuel pressure last summer when I went to a 2 day race school (and could only find 91 octane in Alberta - why does Alberta have the largest petroleum industry in Canada and the best gas you can get there is 91??:hammer and it screwed up the fuel map - I had to have another session of street tuning to get it running again

I adjusted the cams gears on the dyno - but am waiting for Kinetic Motorsports to get their new dyno before doing the rest of the tuning.

note to self--don't touch fuel pressure

good luck with the rest of your dyno tuning and pls let us know your results

I recently bought hondata stage 4 with boost from Prospeed Performance. I have a JRSC on my type r, and the hondata made a huge difference. We did all street tunning, from all different levels of partial throttle to full throttle. He also had a wide band hooked up for best results. We probably spent about 2-3 hours total tunning it to make it run the way I wanted it. I highly recomend street tunning.

truth be told, if your gonna get it done by someone else, make sure its dyno tune. At least that way you know he did somehting. Street tune it yourself. Its free and hopefully you know enough to wher eyou wont screw your engine. I street tune, picked up about 10 Wheel HP. Dyno tuned, got another 6.

Mires

I would do both if I were you. That way you can tune it to get the most power and by the way you drive on the street. About being street reliable, I was under the impression that Jun stage 3 cams are not too streetable.

some guy who i've seen in so cali said he had his jun stage 3's for two years so
far. he's on this board too. i won't reveal who he is cuz i know how people get
about their own personal setups.

i have always read that idle was great with jun III's and they kick *** in high rpms
but some people say they "eat rocker arms" ...
like the cam lobes hit the rocker arms or something....
i wonder if anyone can shed any light on that rocker arm eating deal...

you street tuned by yourself?? nice

was it difficult? and what equipment did you need?

.RJ

we did something similar on a friend's eclipse GSX - he was using DSM link, a system not unlike the Hondata.

No local AWD dynos... but the system came with a base map, we just fine tuned it using his laptop and watching the a/f and where the ecu was pulling out timing. 3rd gear pulls worked pretty well. Was not that difficult if you are just patient with it.

Street tuning made a bigger difference than on the dyno for me. I was thrilled with the car after the dyno session, but I was literally amazed at the difference in the car the night before, when we finished street tuning.

If you are going this route, may as well do it right. Street tuning will allow for an accurate map for your cars daily action, part throttle & WOT.

If you find a good a good dyno, they should have partial load ability. You still can't simulate real air coming into the bay though. Fans can only do so much.

That's not true. If you have a decent dyno - meaning non-momentum - then you can tune at any throttle or load level you wish. Examples are the dynapack and some (all?) Mustang dyno's.
