ECU remap, nitrous, & supercharger

The 1st kit i'm going to sell is a wet kit so that most of the fuel is sprayed through the fogger nozles. The memory adaptor has a plug on it for a single wire which you will hook up to the throttle switch from your nitrous oxide system. When that switch activates your nitrous it will also send a voltage to the memory adaptor telling it to switch to a second set of code. The code located at that second location will fine tune the air fuel mixture and use a much less advanced timing map. Both giving more power and making the system much much safer. You're pretty ballsy to be running nitrous on a 10:1 compression engine with as much timing advance as the svx has (our ignition advance goes as high as 50 degrees). I chose to offer this kit first in order to keep entry level price down as it doesn't require new fuel injectors.

I will be offer a 2nd kit later which includes NISMO 555cc injectors and a dry nitrous system. Because of the injectors though, that kit will cost twice as much. Nismo injectors are expensive and lesser injectors just aren't good enough to consider.

The problem with trying to go half and half with the stuff I'm offering and with your kit is that it bumps up the fuel pressure alot and will completely screw up the fuel tuning. I hate to tell you to scrap what you've got but the best thing to do might be ebay your current kit then get the complete set up from us.

i guess i was under the influence that your ECU upgrade was tunable? Are you including software to adjust the maps or am i mistaken?

With a 100 shot my 175k motor had no problems what so ever. I normally run a 50 shot while cruising around town. When running 100 dry i use 104 as well.

Scrapping my kit is not an option I dont have much money at all, im in debt up to my head with college . All i really need is to get rid of the 6500rpm fuel cut, its incredibly dangerous to bounce off fule cut with nitrous, so i end up shifting way early,

the twin knock sensors do a good job of pulling timing it seems,as zero audible knock is heard witbn 100-120 dry

No, it's not user tuneable. Hey if you feel safe doing what you are doing do it.

You hear an audible knock?

No i dont hear any audible knock when running high dry shots of nitrous.

Wha, What are you talking about? That has nothing to do with why I want Nitrous. No really, I don't know where you would get that idea from?

The kit will include everything. Edelbrock is making us custom kits to our specs specifically for the svx. We then add in a memory adaptor with two sets of code which switches to the second set of code when the nitrous is engaged. That allows us to fine tune one set of code for more horse power daily driving and another set of code with both the ignition advance retard it so there is no detonation and the air fuel ratio for optimal horsepower under nitrous (a lower afr than without). Well be putting approximately an additional 100 hp to the wheels. We expect to charge $1049 for the whole works.

I like the sounds of that. About how much HP are you expecting with the off nitrous codes? How much development time do you need?

I probably won't get nitrous but still curious about the whole deal.

Ooops. Missed the "zero" in that sentence above. :-)

I changed the rev limit to 7400 rpms today.

[Subafreak]

Cool.

[Chicane]

Nevermind.

I would be very interested to know how you did this. Do you have a way to get into the ECU/TCU? I thought the powerband peaked at 5400 rpms or so. Do you expect a change after turbocharging?

Chuck, forget to read the other posts and the title of the thread?

I changed the rpm limit for the sake of those running 5 speeds who want it raised and one person in particular talking about changing his cam timing.

Chuck,

My appologies for being grumpy. It's just frustrating after spending so much time pouring over code to try and keep up with informing everyone on progress and finding out what everyone wants to handle questions that were covered by previous posts.
