Yeah... true. "You've got to pay to play" and all that. If nothing else, it's nice to see the aftermarket picking up for the Fit... and I'd still like to see a dyno chart or at least some numbers for the 5 lb. kit.

 

yeah, finally some real performance mods.

I would like to see a dyno for the 5lb kit too. To see the power curve.

 

Load:
The bypass valve will open and shut progressively. It is controlled by vacuum, and so it is completely shut above 0 vacuum. You will have to datalog specifically to find the Load Percentage number you are looking for, but that is just a number.

Exhaust:
Jackson Racing will be offering a full cat-back exhaust system. No pricing on this system has been done.

Vacuum actuated. That answers the question. And it makes sense. That way it can gradually open and close the bypass valve.

So much for the ScanGuageII to figure it out then. I don't think I'll get a vacuum guage to monitor it.

Thanks Oscar Jackson Jr. for the answer.

 

Mr. Jackson, it would be awesome to see a full graph including boost and afr if possible (to demonstrate the ability of the rotrex unit and safety of the tune). Thanks for coming to the aide of us small Honda fans. You, Sir, are my hero.

 

Boosting up hills can cause detonation. Its more strain on the motor, and since its already under strain (boost) its twice as much.
I dont boost up hills, and I DONT boost in 5th. Its an overdrive.

Those numbers are pretty tastie! And the fact that theyre in a Fit ever better. Id like to see some track times. More interested inn MPH than 1/4 mile times.

 

Wouldn't it start boosting when you go up a hill?
Just when I thought I had it.

 

I'd say it depends on how thourough the tune is...properly tuned with good gas, you should be able to run hills with no issues. What Mx6GT89 says is generally true though for overdrive gears, na or poweradder. It is all about giving your engine a mechanical advantage...running higher RPM at lower load, the engine has more inertia than lower RPM high load situations where it would tend to bog, and detonation creeps in.

 

Question to Oscar Jackson Jr.:

You have mentioned the throttle issues somewhere in this post and I am not sure how to check whether China's FIT version could use JR's product? What is the difference Cable vs. Wire?

I am very interesting for the 10psi one but I am wondering and worry that how I am going to have my "Hondata Reflash" done (i.e. must ship all over from China to US? Any other solutions?) and whether the revised Jackson Racing Electronics plugs will fit? And same as the fuel injectors?

-------------------------
The 10lb kit uses-
Hondata Reflash
Revised Jackson Racing Electronics
Big Injectors
10lb Pulley
10lb Belt
-------------------------

By the way, China FIT club more than 2k+ customers waiting for your answer!

 

Ok so... I had a good post going and it got deleted ... so let me see if I get this right....


Hill Climbing and Tuning:

When you begin to climb a hill, a higher load is put on the engine. This causes the engine to go into boost. Our kits have proper tuning, and have no problem in 5th gear under high load. We have driven the car in 5th gear throughout the Rockies, without a problem.


Cable Throttle vs. Drive-By-Wire:

A cable system is when the throttle pedal is directly connected to the throttle body by a cable. When the engine is off you can press the pedal and hear the plate open and close.

A drive-by-wire (aka fly-by-wire) system is when the throttle pedal is not directly connected to the throttle body. When you press the pedal, it sends a signal to the ECU, which then sends a signal to the throttle body.

The US Fit has a drive-by-wire system. I have heard this is unique to the US, but I may be wrong. Please let me know what system is used throughout the world.

International FIT-up:

Our kits, in theory, should fit other Fits and Jazz with the same engine compartment layout. The concern is electronics. Our 5lb would hopefully work, because it does not care the throttle type. The 10lb is the concern. With the ECU most likely being different due to the drive-by-wire, we have no way of fueling the 10lb kit.

So at this point I cannot guarantee anything overseas, both 5lb and 10lb. We will hopefully get some more information on foreign Fit/Jazz to make a decision. I'm sorry if this does not help, but we just need more information.

Thank you both: Oscar Jackson Jr. and sonorliteman,

That answered that.

When I said "the boost would be nice going up hills". I didn't mean flooring it.

Perhaps that's what Mx6GT89 thought I meant.
I just meant normal daily driving and I always use the proper gear for conditions. So bogging it down isn't an issue.

The hills I run daily are mainly one that I loose about 5mph on in 5th at 70mph it drops to about 65mph by the time I get to the top about 1/4 mile.
The other is a 1.5 mile grade (I call it a hill, they call it a Mountain) which I drop to 4th for once I start loosing momentum and maintain 60 to 65mph to the top.

Put it this way I LIVE ON GRANT MOUNTAIN.

I'm thinking you're cruising along and there are hills you start up one and as the load increases the bypass valve starts to gradually close and the boost gradually begins to increase. If it reaches the load that activates the bypass valve that is.

Obviously you would get used to how the boost feels and sounds (the old ones you could tell by the whine, the rotrex I suspect will be a lot quieter) and would shift accordingly.

So I do have it.

 

You can "floor" it up hills in any gear with our kit. You will have no problems.

-Oscar Jr.

 

That's good to know. I'll keep that in mind.
Thanks for taking the time to make things clear.

Are there any updates on a release date?

 

What kind of information do you need? I'll be more that happy to try to get it for you!

I've been waiting for an SC for the past 3 years....

 

That's exactly what I wanted to hear.

 

OMG! I wish that JR could consider Fit freak around the world! Especially, you mentioned the US Fit has a drive-by-wire system that may be is unique to the US only!

I wish JR would consider the population around the world! Like for China - FIT is 1 million+! That should be a very juiceful market!

 

China FIT,

I never said Jackson Racing was not going to offer an international kit. I said that at the current time, we do not know if our kit fits the rest of the world. I should of said "When the kit is initially released, it will be for American Fits, with other countries to follow."

We understand the market internationally, and would love to offer the kit. But first, we must do our homework. This ensures that when you buy the kit it fits and works correctly, and that you do not have any problems.

Please do not interpret this incorrectly. We are just trying offer the consumer the best possible kit.

Thanks for understanding and your input. It is greatly appreciated. Thanks for the support in China as well!

-Oscar Jr.

 

Would you guys accept payment in the form of a kidney? That's about the only way I can afford this right now. :P

As for installation of the unit, do you guys offer in house installation or any mechanics you'd recommend?

 

Mr. Jackson,

Given the limited production of manual transmissions for the US FIT, can you expand on the information regarding the AT version. (being one of them!)

Cost Differnece?
Both 5 & 10lbs versions available?
Will the "S" mode paddle shifters still work without issues?
same HP ratings?
etc.

many thanks in advance for any information!
best
James

 

Good questions. I'd also like to know if the stock tranny can handle the extra power without causing a reliability issue.
