Boost table switching?!

[T3Bunny]

WOW, there is an INSANE amount of table swapping avalible in these...

I am setting my water injection up to run off the DT table 2. I LOVE that this is avalible from within the MsnSe stuff! Anyways I am setting it up to run the table switching for the second set of fuel maps and spark maps. I also have it swapping boost maps. All of this is occuring when pin 6 goes low. A couple questions though...

1) I want the WI maps on table 2 to be ONLY affected by rpm and map. IE no corrections for engine temp like the normal fuel maps are. Is this possible or even neccisary?

2) When pin 6 goes low, O2 correction goes off, but how about IAT? I thought it also got turned off momentarly?

Jamie,

I assume that James and Phil snagged all the DT stuff completely, so I'm going to say "yes." Just turn off the GammaE on table 2 and you get no AE, WUE, ASE or any of that stuff (my original plan for use of DT was for WI and Guy's was for PWM nitrous control, so we had exactly that same concern and thus Guy and I implemented the ability to run "pure" PWs calculated directly from the VE table with nothing else).

But of course, just as Eric says. It is on the fuel table selection menu.

COOL! Richard Lamb of ERL figured out how I can run the Aquamist system 2s from the MS WITHOUT loosing my WI diagnostics and pump control! So I will be wiring her up in a week or so for WI control through the MS. So my MF2 will retain full control over the Aquamist pump.

Now I need gauges! PWM is easily taken care of. But I also want a gauge of the actual ml/m delivery rate. The middle pin of the water pump sends out a signal thats supposedly directly proportional to flow... I will be scoping this and seeing what I can do with it. It would be sweet if its a 0-5v signal!

Worse case (since I am usally electronics challenged) I will get one of their flow sensors and then it should be an easy hookup.

Do any of you guys know of another 0-5v flow sensor out there? I SWEAR I saw one on a MSers site... DigiKey didn't seem to have anything.

Hi there,
IIRC Im certain O2 correction is not switched off by JP1 pin 6, with water inj it is turned off if using the settings in the water inj section and output X2/X3.

It does if you tell it your running either NOS or Water Injection.

Both use pin6 jp1 (on v2.2) to see the "activation" signal. I will probally tell the MS it its NOS. I just won't have any ignition retard set. One small step at a time... I am fixing my wideband wiring setup at the moment, then back to wiring up the WI interface.

Cool, thats OK then, as long as you knew that, thats all I was pointing out. It doesnt automatically switch EGO off when it gets an input ,

Do share, the Aquamist is a popular tidbit for you boost junkies.

I have just checked the circutry, the MF2 will see the MS's IDC if you connect the MF2's brown wire to the pulsed side of solenoid valve. I think the MF2's diagnostic circuitry will work.

The two wires you need to use is on the MF2 to make the diagnostic circuitry to work is brown and grey.

The brown will tee into your MS's pulse wire amd the grey should remain connected to the water pressure switch (806-162). Leave the red wire connected to a switched +12V.

This is the description for the system 2s that I have. Its NOT the likely system somebody would purchase to interface with the MS though due to its cost... A better way is probally to use the system 2c. Since this one doesn't have diagnostics, you need the DD3 gauge. The system 2d would also work if you fiddle with the setup and condition an injector signal output from the MS.

Unfortuantly all of the above ideas are yet untried. The ONLY one thats a surfire bet is to use the system 2c with the high speed valve and then add to it the DD3 Gauge/diagnostics setup. Its kinda costly though. I think even that rig is going to hit $1000.... I paid about $1200 for mine many years ago when I thought high performance stuff HAD to cost "HIGH performance money" !!!

I will probally do some sort of writeup on this though just in case somebody else can use this information. Its not going to be a simple setup from a configurations point either...

A DD3 setup could be used with a shurflow type system to give it full diagnostics...

HAHAHAHA, evil post number 666!

I have actually! I have been REALY busy doing installs on other rides lately. We just got a whole new harness and power delivery system into my car a few weeks ago, and ran out of time before I left for some installs.

Tonight I am redoing some internal mods so my ECU plugs into the new harness, then the weekend we start playing with the Aquamist again! I have actualy been taking it kinda slow with this as I am working towards offering a full water injection kit hopefully before the end of the summer.

I am in dire need of reactivating the water injection. Cold I can boost 14psi easy. When she warms up, the lack of an intercooler drops me down to only 6-7psi.
