That logic is pretty much the logic i wrote on the link with maths, VA, and GP Pwm tables. While we made improvements with stock AWD Tuning, the switch to Link unlocked a lot more potential. And at the end of the day you need to exactly know what the center diff is doing when you tune your suspension setup properly.

TP vs RPM and PR vs RPM on 4D might work

I have done lots of development on this engine! Including ground braking 5-stage dry sump kit. 1250 Nm at 3500 and 1100 PS :-D https://www.maptec.ch/product-page/maptec-B58-Ultimate-PI-1100PS-Race-Engine You can PM me.

Yes, but you need a extra Licence for .CSV imports. We have a few professional race teams customers who use it.

Yes, we reverse engineered the Renault Megane RS 3 and replaced the stock ECU with Link Furry. We used a AIM Dash, so the OEM dash is not fully integrated yet. However, it is something we can do, if we get enough requests for the ECU Kit.

G5 + the new DI expansion Job will do exactly that. Just bigger and better!

I totally agree, this would make sense. Also, a long term trim function for Wastegate duty cycle would be great.

the function is already there for a few years!

Just use Virtual Aux, several GP PWM Tables and math to combine anything.

It would be great, if you can build in a second CAN output stream, so the Link CAN Lambda can be used like a MoTeC LTC. Also 3th part devices have sometimes templates for the MoTeC LTC and not for the Link CAN Lambda. There is a good market for it, because of the supply chain issue.

I have done the stock ACD ECU and worked out a stragey on G4X to control Center differentials with 3 different maps for acceleration, and 3 maps for braking. Additionally, there is a slip and steering angle overlay. Works quite good!

We need many more target lambda tables, like for: post start ECT based IAT based Exhaust Temp Throttle Position average load based knock fuel trims (apply target trim instead of enrich, which the CL pulls back) NOS compensation two separate targets for Multi fuel mode Launch One way I can think of to do it, is use 4,5,6D and better some more tables as a target lambda or target lambda trim instead of a fuel trim. However, the ECU should just use the richest target within the calibration, so it doesn't get too rich when several conditions are meet. Like high IAT, ECT and Exhaust Temp, which are usually hit at the same time. Using target modifier for each condition, would end up in extensively rich target lambda.

That's exactly what I did for testing. However, there should be some additional conditions used like PT1- like reduction of fuel de-enrichment, coolant temp compensation, and all the stuff which is used in the acceleration model, just with a negative sign, before it is applied to the fuel model.

When the Throttle is suddenly lifted, lambda values go much to rich, do to the small delay in MAP reading and the fuel film puddle in the ports are sucked into the cylinder. I like to see a deceleration enrichment which removes fuel in these situations. Wondering if other tuners are missing this too?

good suggestions I would also add a time delay to each filter setting. So for example when transient rpm was detected, mixture map sampling is delayed by X secs or better engine cycles until Lambda reading has stabilized
