I'm sorry I have searched and found a few relevant (but archived) threads -- but none of them really answered my questions.

I'm an all-motor guy by heart, but a nitrous guy by wallet. My current setup is an internally stock B16B, intake, header, exhaust (not really, moreso just open -- long story lol), clutch, 4.9 final, cusco LSD. i'm planning motor mounts soon and an 85x89 build one of these days. However, I'd like to 1) try nitrous out because i've never had it on one of my cars and 2) set some good times before the motor build.

However, this is my daily and I'd like it to last at least for a little while -- so I'm planning on a wet 75 tuned on Crome with correct colder plugs. Anything else I may need? (ignition/fuel pump?/injectors?)

My problem is, I would prefer to run the car NA most of the time, and only use nitrous on the nights that I feel like it. I'd like to have it tuned strong NA (with corresponding plugs as well) and then be able to switch quickly and easily to a nitrous setup (change plugs, change tune).

1) I don't know much about Crome software and i would just ask my tuner, but he is currently pretty busy.. so I'm just wondering if the Crome software has adequate capabilities for what I'm doing?

2) Is there a way to place 2 separate maps on a toggle switch? or will i have to pull/swap chips? (not that it's that big of a deal, but it'd be cool)

appreciate any help, and sorry again if it's rehash.

EDIT: The nitrous tune would be on 110, the NA tune on 93. And, in case you were wondering the CR of a stock B16B is 10.8:1.

1. Crome does not have nitrous control.
2. Yes there is, using an ems such as hondata s300, neptune, ectune that supports dual maps. You can also use crome with a two timer chip module and an sst512 eprom chip.

I would recommend using dual mapping and nitrous control to properly tune a car on nitrous.

I would suggest Hondata s300, Neptune RTP or eCtune if you can afford them

 

i've always said if you can't afford it don't do it, I found the nitrous thread (after posting this, because i'm a tard) and read it.. most likely going with eCTune or the Hondata.

thanks for your help i appreciate it!

 

On Crome you can actually run 2 chips in the ecu, and run a wire out of the ecu and have it on a switch. Switch it (On) if you want your nitrous map, or switch it (Off) if you want your all motor map.

I ran a similar setup, my local Crome tuner set it up, i can contact him and see if he has any more dual chips, or more info for you


Just have the Nitrous chip on when you want to spray it. It will be hard since there is no nitrous tuning with crome, but a good tuner can figure it out.

 

The S300 Nitrous Control works really good. So does the Neptune RTP.

 

wow man that's awesome i'd appreciate any info you could give me.

any details on the specifics of nitrous control? i'm no tuner so my knowledge on tuning is limited, trying to learn though.

thanks guys

Do you guys use the ecu to control the solenoids over there? Typically how much timing do you remove with nitrous 1-2 degrees per 25 bhp ? have pushed quite hard on a chip set over here with no problems but no doubt the timing is quite relaxed to cope with the people that do what i did or run 30 psi when it says 20 psi never pushed my luck to much mind you and kept it fairly rich.

The ECU is used to control the solenoid based on certain parameters like load, rpm, throttle, etc. Basically with NepTune you can have the basic control, which is adding fuel and pulling timing for different rpm points, or you can have complete control where it will switch to a secondary set of maps when the nitrous is activated so you can fully tune those secondary maps for the nitrous. I'm pretty sure Hondata can do the same nowadays.

That's exactly what I need, the complete control where a nitrous map is activated simultaneously with the nitrous. More for convenience than anything though, because i want to have more time to use racing at the track vs. setting my car up to do it.

thanks again

 

No problem.

Thanks for useful reply. I can use RPM and TPS on my nitrous controller. what are your thoughts on amounts of timing to pull vs shot used?

 

btw, i checked out the Neptune RTP on the site and due to your help and the information I found i'm definitely going with the RTP

I actually can't suggest specific amounts as it will vary for each setup. Best way is to tune it out properly on a dyno.

Awesome. You won't be disappointed.

Dose the S300 even work with "WET" kits i thought it was only dry kits???

 

u can set parameters in Crome GOLD with the use of one of the inputs on the ECU to control timing and fuel.

Why would it not?

 

Look on hondata's home page it only says it supports the dry kits (under s100, s200, and s300). And if you look under K-Pro it says it supports both wet and dry. Somthing i would like to know...

You are confused.

ECU is just trigging a relay. It does not matter if it is wet or dry. You can have fuel/ignition correction for both.
