Under what menu option using the wintec software can I setup the two-step on my purple Tec3? Does tec3 have this feature?

What are you doing over here

Go to sensor parameters set your default in th MAT to -30
This is where it will go when you ground your IAT.Now go to
fuel enrichments then MAT -30 block this is where you wil add fuel.
Last but not least your timing map at the bottom has the MAT advance retard this is where you will pull timing in the -30 block.Experiment with these settings as you can make it a two step or anti lag depending where your settings are.

Whats up CC...I needed info for the TEC3 man

We are trying to prep the car for those good 1/4 times. Thanks for the info, I will take a look at it sometimes this week and play with it...Hopefully my neighbors windows won't shadder

CC,
Can you elaborate on the 2-step versus antilag settings? Would it different on the silver TEC3R? Have you used it for anti-lag and if so, did you monitor EGT and have any info on what one might expect with temperatures? Someone should do a step-by-step or how-to for both the topics and make it a sticky. Thanks.

Two step/anti lag it all depends on how much fuel you add and how much timing you take out...extra fuel and taking out alot of timing =Antilag

Can you give examples of what numbers you are using - my MAT settings are at:
Sensor
MAT high volt = 5
MAT low volt = 0.04
MAT failure default = 72 degrees C (understand this should be changed to -30)

Fuel enrichment
MAT -30C = 2

MAT advance retard
MAT -30 = 0

What numbers are you using for 2-step and what for antilag - what would be good starting point for either? Thanks.

it is somthing you have to experiment with keep pulling timing and then adding a little fuel until you get the boost you want.Try somthing like this

Fuel enrichment
MAT -30C = 5

MAT advance retard
MAT -30 = -3

How do you get the MAT to go into default? You say to ground the Intake Air Temp Sensor? Do you do that with a manual switch? And if so how does that work when you launch? I get the idea of how the different settings will affect the engine just don't understand how it will be turned on/off.

I use a momentary toggle on while holding it ,when I let go it goes back to normal

On my RX-7 I currently have the MAT wire grounding to sensor ground through the clutch switch with the circuit being controlled by an on/off toggle mounted on the instrument panel. With the switch on, and the clutch depressed, the aux rev limiter seems like nothing more than a misfire as the engine can easily over-run the auxiliary rev limit. So I read the following:




Now what is happening is that when I switch on the aux rev limiter and push in the clutch, the engine stalls.

How do I configure the rev limiter to not exceed the set RPM, but also not stall when engaged?

Thanks for the help!

Does anyone know what appropriate fuel and timing settings would be for a 13B rotary?

What will owrk best depends on a few things. I can't rememeber if you are running a turbo or not. Also what are you trying to accomplish by using the secondary revlimiter? If you are NOT running a turbo, cardcounters solution may be why you where stalling the engine. If you have an NA motor, you don't want to add fuel because it just makes your exhaust really hot. With a turbo, that's useful because it will help you build boost on the line. Also, if you are actaully looking to launch with it, the solution is different than if you are just trying to do a flat shift.

Let's start with what you need to accomplish and go from there.

The engine is currently NA. I'm looking to use the rev limiter to hold a specific RPM for launch and so that I can no-lift shift.

Thanks

NA motor are significanly easier to deal with. Honestly, almost anything you do should work pretty well. I assume that you alrady have you clutch switch grounding the MAT line to activate the revlimiter? If you don't that's what you need.

Then set the secondary revlimit RPM in the Revlimit screen in WinTEC to the RPM you want for launch (this applies to both WT3 and WT4). Finally, you'll need to setup the revlimit strategy. I recommend that you start with 0 deg advance, no fuel cut. This should stop an NA motor in it's tracks and be the least harsh limiter (not to mention the easiest option on a Rotory engine). The Launch limit I would imagine will be somewhat below the RPM at which you will be trying to shift so that will be taken care of as well. If/when you add a turbo, I'm certain almost all of the options will hcange to something else, but we can discuss that when it happens.

Good luck.

So I need to enter 0deg advance as the value for -30 in the MAT Advance/Retard screen (after setting -30deg as the default sensor failure value)?

Thanks for the help!
