Hondata Reflash+Nitrous Oxide, NO?!?!

SpeedDemon · 10-16-2007, 07:42 PM

Today, I decided to talk to every shop possible on having a Nitrous Oxide kit with a Hondata Reflash cause I will be getting that in the future. One shop suggested that I didnt go with a 75shot, because in the future it might weaken my engine and it wont be running right.

Second shop told me that its fine, and perfect thing to do, and they will do it safely

Now after those shops, I went to a Hondata Dealer near me, and they told me that it wont be recommended to run a Nitrous Oxide kit with a Hondata Reflash due to the the damage that it will do to my Engine.

I called Hondata, asking them if it will be possible to run a Nitrous Oxide kit with their Reflash and they told me no, for the reason that it will damage the internals very quickly.

So.. Im very iffy, need your help guys.

From Hondata themselves

"Nitrous has not been tested. As ignition timing has not been changed, nitrous is as safe to run with this reflash as with a stock ECU."

Well its hard to believe when you have Hondata themselves saying No. And their local Dealer near me, saying it wouldnt be recommended. And also a Friend, that once had Hondata Reflash in his car, but he ended up selling it cause after he started spraying he started having major problems with the Si.

Why would Hondata say that I cant use it with my Reflash?

And yes, I read that on hondata, that its as safe as running it on a stock ECU, but still.

Are they just trying to save their asses from getting sued?

Highrev1 · 10-16-2007, 08:19 PM

Maybee, maybee they think a 75 was a bit too much. I dunno they are a well respected company and don't want to lose that, CYA Cover Your Ass, thats key in the world we live in today..

I spoke with Shawn Church about running nitrous with hondata reflash and he said no. It messes up with the valve timing not a good idea.

Highrev1 · 10-16-2007, 08:39 PM

Well then there you have it Listen to Church!!!

For real.

I dont plan on running a Nitrous Oxide kit then.

Thanks for the confirmation.

This is an excellent question about using nitrous with Hondata. With my G35, the company that does reprogramming of the ECU is Technosquare. They will do a special reflash if you specify nitrous. They are categorical not to run nitrous with their normal reprogramming.

This from their site:
Can I run NOS?
DRY SHOT
The ignition and fuel mapping will NOT be changed. The reason they are not touched is due to the nitrous leaning out the air fuel mixture. Our ECU upgrade program will safely lean out the stock setup. However, with a Dry Shot, it will lean the fuel mixture out way too much and causing detonation and possible engine damage. With the Dry Shot we can still raise the rev limiter, cut the speed limiter, remove of the feedback/detuning control loop, and remap the drive by wire.

WET SHOT
On a NOS Wet System we can modify the ignition and fuel maps since fuel and NOS is mixed together for the shot.

SpeedDemon, I did some research on the Zex kit. Looks like their kit provides a full throttle switch. However, you will need to add the window map switch. I found this on their site:
http://www.compperformancegroupstore...OUSACCESSORIES

Traction Control Window Switch
PART #82085

Let's you select what rpm the nitrous activates and deactivates
Allows you to select what gear the nitrous starts spraying in
Fully programmable and adjustable up to 20,000 rpm
Easy installation with complete instructions

Thank you, been looking for that.

I actually think that the only solution that would be safe for me would be have it activated with that switch to engage from 4krpms-7.5krpms so that I dont stress out the internals.

Now the thing is, would still mess up my valves if I had it set like that?

No, you will be fine. Your kick in point is a little conservative actually. Try around 3,500 rpm. Your phase out is fine. This won't affect the valves because the nitrous is only activated at full throttle and not at low rpms. The motor will be in the fat part of the power curve. Phasing out at 7,500 rpm gives you some wiggle room. You should be good to go.

SpeedDemon · 10-17-2007, 07:05 PM

I was thinking today, maybe a 55shot would be less stressful.

The beauty of nitrous is the tuning ability it has. You can start with a 55 shot. If you are not pleased with that, you can go up to a 75 shot. Anything after that gets a little iffy. You can always rejet your kit for a 75 shot at a later time.

Personally, I would go with a 75 shot because the K20z3 motor is pretty stout. If you have the proper safeguards, you should be fine.

SpeedDemon · 10-20-2007, 12:05 PM

I ended up not installing the Nitrous Oxide in my car.

Really dont know how all you people can put that on your Si, when in the long run it wont be good.

I drove my car 4hours yesterday going to the track, and was really satisfied with my cars pull, so I dont think I will be adding that in my car.

I will post the pics of the Nitrous Kit soon in the for sale area.

im sure theyll eventually lower there prices and dont you get more hp outta of redshift

GlxyGry06Si · 10-20-2007, 12:20 PM

you do get more hp but comptech is a super reliable brand. as well as jr. i had never heard of redshift before i heard about them on here. plus im not looking for a 360 hp car. the 50-80 that i get from a comptech or jr will be plenty. wanna talk about stress of nitrous on a car always have a lotta boost on a car.

nitrous=stress
360 hp supercharger=stress
comptech or jr=just right for me
