Just what I see... just how you stated what you see. I worked for Honda for a quite some time selling Fit's to many members of this site... The Majority then was still people over 30. not saying that 30 is old, but usually arent in the "tuning" of Honda's.


Then why is everyone still waiting and crying for a bolt on kit for the USDM fit? CERTAIN things will fit from those kits.. but others will still need to be modified to fit correctly.

no it wasn't... LOOK...

Anyways.. I'm done with this thread cause its not getting made anyway.

 

Thanks for supporting your fellow Fit owners.

You really didn't add much in terms of intelligent discussion...but
thanks for stopping in I guess

 

I find it interesting that Hondata would take a risk putting in the R&D $ on a car that hasn't been out too long as opposed to the the Fit which has been on the market for over 10 years in different variations of course. I can see the argument from both sides where the average age for the Fit is higher than the CRZ and people who buy the Fit are more likely to care about MPGs rather than performance but the same could almost be said for the CRZ. I mean after all it is still a hybrid but the since it's basically a coupe/2 seater car which would make it a bit sportier I could see an argument for that as well. I would like Hondata to make flash pro for the Fit if only to solve the rev hang and maybe boost the red line up a bit for fun.

 

My thoughts exactly. A lot of people are betting big on the CRZ. I believe people who want to modify the CRZ do not want to deal with the IMA system...on the other hand, people who want to modify the Fit want to push the L15 to its full potential. Therefore, I think most people are going to K-swap the CRZ and remove the electrical IMA (dead weight)...whereas most fit owners would be content to boost or build up a NA motor. Following this line of thinking, you don't need a CRZ specific Flash-Pro for a K-swap...you just need a K-series ECU and K-pro. Just my thoughts.

You don't need flash pro for that...you just need a reflash. In fact, you can buy it now. Contact this gentleman...he will need your USDM ECU in exchange for a flashed version.

Thanks blackndecker for pursuing this. This might get us nowhere, but it never hurts to try. So no need for any negative comment towards a guy who just simply wants something done for his car.

blackndecker, your link got me interested though. Do you know of anyone that has successfully reflashed their USDM ecu? A few knowlegeable member spoke of how Hondata is not the only solution, but i haven't actually read any member on this forum that has gotten their ECU modified/reflashed.

From my search on the forum, only one member had their ecu reflashed, and it was on a JDM vehicle (555sexydrive).

 

The gentleman I linked you to WILL FLASH YOUR ECU for you. Step out into the abyss and push the envelope.

Right now, I have too much cash flowing into my k24 swapped civic to start diving into the Fit. Maybe this spring I will be finished with the civic and I can get serious with the Fit.

 

has anyone done it successfully on a USDM car?

i understand singapore also has the JDM 1.5 RS variant of the Fit. I don't know if there's any differences between the JDM fit and USDM fit.

 

Step out into the abyss and push the envelope. The worst that can happen is it won't work.

 

Here's a thought about that. Those that are serious about a reflash, collectively put money into buying a new stock ECU from Honda and send it over to be reflashed. When it comes back and works, something can be worked out between all those that contributed and the others would then feel comfortable about sending their ECU over to be reflashed.

 

That's a good idea.

I've actually been searching online and I found many USDM 09+ Fit ECUs for $100-200. I'm not sure of the actual cost of the reflash but I think this is probably negotiable with Henry Wang. We also have to consider the cost of the Uni-chip tuner and dyno time. I think the whole ball of yarn could be had for $1000. The problem is going to be finding someone reliable enough to trust to actually get all this installed and dynoed. I think LyonKnightRoad is the only person I'd trust on here...seeing as how he's commited to blowing up as many L15s as possible!!!

 

Why on earth would he want a reflash? For $1000 it better come with a 5 diamond hooker and an eightball.

 

Correct me if I'm wrong here DSM, but I figured a flashed ECU would be less "adaptive" to modifications. Some other changes were flashed into the ECU as well like increasing the redline...but I can't remember all the specifics at this time.

Is a flashed ECU easier to tune? Or is that just a function of the piggyback controller?

 

Standalone > Flashable ECU > Piggyback > S-AFC > Reflash/Chip

I think you may have a couple of these mixed up.

A reflash, is just a "permanent" parameter change. In order to change this you would have to send it back to the person/group that burned it. This is the least comprehensive and cannot really adapt to much of anything. The settings you get, regardless of whether they compliment your setup or changes in the future, are the ones you are stuck with.

This is relying on the group to have the intuition of how your particular setup likes to run in the environent you live in with the fuel you have at your disposal.

An S-AFC in most cases lets you adjust fueling for VE mods, but leaves the ECU parameters intact.

A piggyback is more or less the samebut often with the ability to adjust timing as well as other items depending on the make model (redline/injector latency/etc)

A flashable ECU is where you the end user can tool around with some of the ECUs settings and save them, while getting full data feedback.

A standalone is where you must calibrate everything and is the most adaptable.



At this point in the game, I would be extremely surprised if Lyon would ever consider a non-end user tunable device. Especially for that cost.

 

Thank you for breaking it down in easy to understand examples. I feel that I have a good grasp on the difference between a "reflash" and "flashable ECU" but maybe I'm not articulating this clearly.

This conversation changed directions rather abruptly when adolan21 asked how "to solve the rev hang and maybe boost the red line up a bit for fun" and Mr.Dan asked for more info.

A flashable ECU would not be necessary to increase the redline...though I'm not sure what issue is being referred to as far as "rev hang."


As far as the scenario I outlined above...maybe it wouldn't even be necessary to get the chip flashed...just use a piggy back controller.

DSM, do you know of a way to properly tune the car and not have to worry about a conversion harness for the dash controls? A standalone would be a nightmare for wiring (I don't want to use custom gauges).

 

The rpms hang when shifting gears and just revving the engine because of the ecu trying to be fuel efficient and making sure all the fuel burns. It's extremely noticeable for me when jumping between the 350z and the fit. I hate it and it's a pain in the ass. I really just want to delete every fuel efficient thing in that damn ecu cause I really don't care about the efficiency anymore...

 

^I assume you are referring to the automatic version? I've never noticed this with my manual.

 

Nope. 5 speed Manual. Mine does it. It's annoying. When I left off the accelerator the rpms sit for about a second and a half. In the z I left off the accelerator the rpms drop immediately.

 

Might this be partly due to the flywheel weight used in the Honda Fit? A heavier flywheel will hold revs longer after letting of the accelerator.

 

No its in pretty much all the newer cars like 2005ish and up. my cousins fg2 did it. the fit does it. Rev up to like 4k and take your foot off the gas entirely. The engine will 'hang' for a brief moment before the revs drop. its not a massive thing. If you dont know much about cars, or havent really driven a cable throttle m/t before you wouldnt notice. but its annoying when you know how to drive standard and want the revs to drop NOW lol. Im suprised you havent though B&D

 

Ahh...got you...cable vs. DBW throttle bodies. TBH, I haven't really noticed the rev hang. But, I've never owned a real sports car...the civic I'm building uses a cable TB so it will probably slap me in the face one I start driving it.
