Cool. I'll pm you so I don't jack this thread.

 

Hell that's one of the reasons I started this thread so owners could talk to each other.

 

In that case, feel free to answer my questions in here OD.

 

More like no law against having something hanging that far off the rear bumper. Whether he uses the thrust capabilities of the jet or not, that is a different story.

 

wow, amazing to see that it's LEGAL in California! (of all places)

 

You jest, it's illegal to breath in Cali as the pollutants caused by taking a breath are contributing to global warming.

 

I always thought it was what came out the other end that caused global warming.
It does in this house, anyway...

 

Sweet, I was hearing two trains of thought:
The spray meth before the S/C crowd and the spray meth after the S/C crowd.
I see you thought outside the box....

 

Juan did that to test the theories. I don't recall that he reported his findings.

 

It's amazing that anything is legal in Cali

See SCAQMD Section 1 gases considered pollutants.

I see it's been a while since you've been to Cali

Oh well, we will all have those rules here shortly -

 

On the verge of taxing the air we exhale with the Carbon Credits. When will it be enough to institute Title 18 of the United States Code in dealing with these idiot politicians?

 

Lets speak of the water meth system.
I have a snows unit and havent installed yet. I probably will use the pre blower site with a 175 injector?
I will get a solenoid regardless and a large tank for trunk use.
My question is --ok the water meth by how much does this protect against detonation? Can you run a 13.s a/f with conservative timing with the water meth?
More questions later--gotta go to soccer game.

I don't think that alky injection was ever intended to compensate for lean A/Fs nor improper ignition curves. It was intended for use in situations where the fuel quality may not be in-synch with the boost desires. Let's look at it another way; what octane fuel could safely be used with 8-9 psi/manifold boost and 13:1 A/Fs? The thing is, when one has the proper numbers available, without alky, that's what we should shoot for, first.

 

Water/meth injection is a preservation scheme.
I've always felt that, as a tuning tool, it was a band-aid at best.
That said, I will be running water/meth injection as soon as possible to allow me to continue operating my car as I have it tuned now under the significantly more abusive conditions of the Phoenix summer heat and craptastic gas.

BTW - I have the AccessPORT tuned for the Pettit setup, so anyone that is running some other form of flash or engine management might want to consider a change.
The AccessPORT allows for OE-like start-up, idle, power delivery and emissions compliance and can be individually tuned to fit the various changes Pettit users have implemented in their systems.
You can flash your PCM over and over again with newer or different calibrations to suit your needs and can address other areas of drivability and engine longevity that the other systems do not.

 

He had a red flag hanging off of it, but it lasted less than a nanosecond!

This is precisely the use for alky.

I haven’t dynode my car since I installed the meth kit. I didn’t installed it to gain horse power but rather to prevent fatal detonation and most important to bring the intake temps down mainly for AutoX events. If you haven’t taken part in an AutoX event it usually goes this way. Your heat or vehicle classification is called. Then you have to stage and wait your turn to go (this can take 1 to 5 minutes). By then your car is hot and the engine bay is screaming. Finally is time to step on the throttle for a good 25 to 50 plus seconds at high rpms and if you are lucky (depending on the course) up to third gear. Most of the courses are run mostly on second gear. Helloooo engine stress!!!

Therefore, in order to attenuate these harsh engine conditions, I opted to upgrade the OEM radiator to a BHR radiator and the meth kit to bring down the intake air temps since the SC intercooler system is pretty much useless while crawling to the start line. Air/track temps can be very brutal during the summer time here in Florida.

When I first ran the meth kit I was experiencing random misfire at high rpms. While waiting for MM to start experimenting with the LS2 ignition coils I was able to get rid of the misfire conditions by changing the OEM leading spark plugs for NGKs 11.5 (I had a pair of them in my R100). Racing Beat recommends 10.5 for Turbo or SC applications. Now that I upgraded my ignition coils to the MSD LS2, I’m planning to run NGKs 10.5 that I just purchased from BHR (once they arrive) for the leading side and move the current 11.5s to the trailing position. Will it work…we shall see and as always, I will provide feedback.

Also, before someone starts wailing “those plugs are too cold”, my car is not a daily city driven car. Most of my driving is on the highway going to and back from an AutoX event.

 

ok i am running the 9's (rx 7 trailing plugs with the spacers).
I THINK i may be hearing a little detonation at very low rpm(closed loop 2-4 K) under very light load(tps maybe at 10-15%) . 93 octane and temps are very cool --coolant at 180F oil about the same, ambient temp at 60F. It goes away with a little more throttle(at maybe 30-40%) (the a/f's do drop but only to the low 13's--there again i am not sure they are accurate---the innovate is calibrated ok.
My newly install innovate is showing in the low 14'sduring these times!! I dont know if that is correct.
I know better than to chase the perfect a/f but Jeff what are your targets?
What maf pipe is your tune coordinated with?
i really need to do some data collection and help here. i want to track my car but not when this is going on. I dont know enough about it except NOT to push her like this..

hey denny...did you get an efidude yet?

 

Calling Cam this morning---

If anyone is interested in an LC1 Wideband, PM me. I've decided not to install it now that I'll be using the EFI Dude.

 

Helleluiah!!!

I hope your giving it away for less than the Dude prologger?

Cheers,
Hymee.

 

I am headed toward a data logger also--but I WILL keep my wideband.
OD

 

Very good idea.

 

generally speaking a wideband is twice as much as the efi dude...
