You can use the generated math channel as:
- logging channel
- input for other function
- axis option on tables
So it's up to your creativity what you can do. Combined with Virtual Aux and timers the possibilies are near endless!
A few example:
Boost error channel = Target Boost - MAP
Boost error parameter can then be used to control an electric Blowoff
Brake bias = (rear+ front break press)/ rear break press
Front Wheelspeed Difference = LF wheel speed - RF wheel speed
Used to tune your LSD differential settings
Slip right = non-wheelspeed - RR wheelspeed
Setup an Aux and turn on a driver warning light on the right side of the dash. So Driver knows right rear wheel is spinning faster ( eg. Attention after a curb) to another function for left. Then it looks like this :-) from 3.00min

I agree ETC table should allow also negative corrections, for "quick and dirty" adjustments. Sometimes you can tune charge temp correction perfect for normal operation temps (60-110 degree coolant temp and 0-80deg IAT) and when you finished with the whole tune, you see next day that the cold start is to rich. Means you need negative ECT trims.

Hi Simon
Why not unlock the function for use with all ECU's? A torque ctrl function will be good for WOT and partload.
-
Yes thats a good suggestion. Even better would be a propper fuel film modell or at least some kind of short and long term acceleration enrichment.

Do you use the lates firmware? It has 9 VA, if I remeber right. Or is rhus still to less for your application?

I'm using fuel cut most of the time to prevent the very hard bangs during shifting. But the downside is, the power cut feels a bit slower.
I would really like if LINK will do a IGN And Fuel cut option.

I like to add another point. I'm really missing a delta function where you have two cursors to see the difference between two points.
Once GPS mapping is possible a distance mode for the X-axis will be needed, too.

Hi
It would be great if you can share you results, regarding high pressure pump, trigger pattern and injector charakterisation.
Thanks.

Sorry if i hijack tjr thread. Why is ign and fuel cut used for rotary and why not also on other engines?
-
Please elaborate what you want to achive. Maybe its already possible.

A easy layout with such button woulf be good for the End-customer. I would like to setup a layout page for the customer so he can access active test and clear of error code. All other areas of the ECU should be protected or even better there should be access control for every setting.

Finally yeeeah!

Aem UEGO Analoge widband is junk. The never ready up the same as my reference lambda on the dyno. I highly recommend the Link CAN-Lambda. They read very accurate.

Currently we support a race car that used to run a complete Motec M1 setup with dash, PDM, ECU etc etc.
He's now got a Fury installed instead of the M130. Engine is running much better... But... Logging is now a massive pain!
Essentially we log all of the engine data and as much as we can via CAN, but we have run out of channels and can't overlay engine data onto a circuit map, so the result is we use MoTec's i2 for viewing data against track maps. The problem with this is we can't get all of the data into the dash from the Fury! So we have to use 2 different log analysis programs...
If Link could implement GPS data I think that would be absolutely awesome. In this case, we could probably move the car over to the Link (AIM) Dash as well and not use i2 at all.
If you have a C-dash you should be aible to program a custome can stream from Furry to Dash with all data you need.

The 2JZ non-VVTI has one Crank and two Cam sensors. Which one is intended to use with the 2jz trigger mode, front or rear one?

Yes indeed, what brand Rotary switches do you prefer?
I'm using AEM 30-2056 and for Highend Application Motec 9 Position. Doesn't matter much which one you use, it just should give you signals between 0 and 5 Volts.
Besides, Adamw / Link ECU that would be a nice Accessory in your product lineup!

If you use a calibration table with Volt input and integer position numbers (1-12) output, the output does only change in steps of 1, so no problem between interpolating. However, if you have a 12 Position Switch for example Launch RPM, the Launch RPM would only change negligible little.

We use up 4 rotary switches on some cars.
12 pos Launch RPM
12 pos Torque Maps, VA to switch between 3 boost strategies (TP, RPM base, straight) with several Boost Targets. Alter IGN on some maps.
12 pos Traction Control Targets
3 Pos Switch for different E-throttle Targets
You can do quite complex setups and much more than the Average Joe may think is possible with LINK. Only limiting factor is the overal number of 30 tables. And 4D,5D,6D would be nice for boost. I would also like to have a few more Fuel and IGN overlay tables (7D,8D,9D...). Same for traction control.

I think its much better to have all universal function like virtual aux, timers, 4D, 5D, fual fuel table etc. than a dedicated NOS function. This way you can build your own NOS function excatly how you want it. You just habe to be a bit creative with the universal functions.

Interested in full Rotary switch support as well, so we could alter for example traction control slip %, als setting ect without the need off VA
You can already do that. Just setup a anloge input for rotary switch. Use eighter direct voltage or use a calibration table to output position.
Use rotary voltage or position as an axis for launch rpm, traction aim, boost aim, etc.

I like to start a thread where everyone can add his Math channels, so a database is built.
Please only post Math channels with short explanation in this thread.
To keep it simple any discussion must be done in other threads.
Boost error channel = Target Boost - MAP
Boost error parameter can then be used to control an electric Blowoff
Brake bias = (rear+ front break press)/ rear break press
Front Wheelspeed Difference = LF wheel speed - RF wheel speed
Used to tune your LSD differential settings
Slip right = nondriven-wheelspeed - RR wheelspeed
Setup an Aux and turn on a driver warning light on the right side of the dash. So Driver knows right rear wheel is spinning faster ( eg. attention after a curb). Add the same function another for left. Then it looks like this :-) from 3.00min
