access port and zex nitrous system
access port and zex nitrous system
i have been looking but cant find anything on using the two at the same time........ or if it is even possible........any help would be much appreciated
Mira... Mira - it's the SAAAME thing!
BTW - AP is a tuning tool; Nitrous is a Mechanical Tool - think hardware vs software - you use them both.
just to add to what has already been said, as charles ray hill tells me, once you have a good tune, a wet nitrous system is just a bolt on (as long as you stay below 55shot) and requires no further tuning.
The only way that a Cobb AccessPort helps a nitrous system to run better is by virtue of the fact that the AP allows us a more optimal tune BEFORE the nitrous is added. For example, an engine that is tuned too rich, even with a properly calibrated nitrous system, will still run too rich when the nitrous is used. Lean out the host engine and everything will work in a more synchronous fashion.
Since the factory PCM was not designed with external triggers/ input channels we are stuck with this scenario.
ok i have the zex wet kit installed with the ap, some plasma direct coils, a cat back, and a hollowed out cat, with 50,000 miles on the motor.... how large of a shot can i run ????
i know absolutely nothing, i thought maybe that would be a baseline to some guidance...i know easy said he needed a lot of tuning to get to the point where hes at...
that is all

Yeah, well..........
The factory PCM is not designed to allow for accomodation of nitrous use. It works for F/I becase that is an airflow-based application and not chemical-based. There is no way to trigger the PCM to toggle between an N/A tune and a nitrous tune, either.

On Erick's car, I have been gradually leaning the low RPM, high load regions to the limit so that it is not entirely too soggy down there.
The areas where the RX-8 is not prone to knock can be run significantly leaner than optimal.
Of course, you would be losing 2% - 5% power there at WOT, but why are you driving WOT with the juice off, anyway?

Yes, you can, and I pioneered it 5 years ago. That was one of the things that led to the creation of BHR. What I was saying is that the factory PCM does not have an aux input channel because Mazda could not have cared less about what we in the aftermarket wanted to do. As such, the best we can do (other than adding a piggyback EMS) is tune the N/A application as best we can and then add about 55-60 h.p. worth of fuel/nitrous on top of that. BHR does have a product idea on the project board that will help us achieve higher shots (like 75-125 h.p.) rather easily.
As for A/T applications Easy_E1's car has been BHR's whipping boy and, although nitrous will work, it has to be handled with caution as the TCM likes to mess things up a bit.

THX that helps I'm thinking my Next Huge Purchases are The Safe Shot and The CobbAP

Could you get me an estimated price for all the above, Zex is all about easy install lol and my paychecks aren't crazy so thats why that zex kit is about 314.96 Thats damn good fo mee
Does the fuel jet know what the airflow is?
Well, yes.
Amongst other things.
But the point is that a fuel jet will introduce the same amount of fuel at all times, regardless of the fact that the engine needs less at low RPMs and more as it reaches the torque peak.
Which is why I taper the fuel delivery in a complimentary fashion.
Not optimal, but certainly less suboptimal than having an over-rich condition down low and far safer than a lean condition up top (where it can actually do damage).

Yep, the big deal is not even picking up the rpm signal, the problem is making a variable jet. A valve on the nitrous line? That could be vacuum operated too. The problem is not talking about it, is crafting it!
I pmd you btw

Its called a solenoid and its how the "big boys" do it.
It is utilized by a "progressive nitrous controller" - something that Easy and I have talked about at length.
However, in regards to the "pragmatism" that Ray is talking about, the fact is that RX-8 customers are mostly cheap bastards and NO2 users are an even cheaper sub-set of customers that are unlikely to spend the money needed for a progressive controller.
They just want to hit that button and see Vin Diesel go streaking by.
