Explode64 Posted May 20, 2016 Report Share Posted May 20, 2016 I have been looking around and haven’t seen anything about using volumetric tuning on a 13B turbo.Is this possible/ common?I ask as im looking at setting up a FD rx7 for flex fuel.Is this common to do using the Link G4+ plug in or G4+ storm black ECU?

race jase Posted May 20, 2016 Report Share Posted May 20, 2016 all the rotary maps i have seen have been tuned in injection time, i just checked all my old haltech files and 90% of engines are tuned in VE except RX 7/8, why im not surehopfully simon or scott will chime in here. jrizing 1 Quote Link to comment Share on other sites More sharing options...
Scott Posted May 20, 2016 Report Share Posted May 20, 2016 Hi guys, my understanding is that there are no problems running a rotary engine on modelled fuel equation. However I will check with the engineering team, and then come back and confirm this. Quote Link to comment Share on other sites More sharing options...
Joe Prostreet Posted May 20, 2016 Report Share Posted May 20, 2016 I've done with modelled fuel equation on a few 13B & 20B engine. It's commom. Quote Link to comment Share on other sites More sharing options...
Rich RDE Posted May 21, 2016 Report Share Posted May 21, 2016 You should absolutely be able to tune VE with this. I have tuned a few. Setting up the flex fuel system is going to be easy compared to other ECU's. Do you have a base file? Make sure to enter all the information correct for the fuels you are using. If you need any help post a base file for us to take a look at. Cheers Quote Link to comment Share on other sites More sharing options...
Explode64 Posted May 21, 2016 Author Report Share Posted May 21, 2016 Im still deciding on which ecu i get. Will both the plug in and storm work in this application? Quote Link to comment Share on other sites More sharing options...
race jase Posted May 21, 2016 Report Share Posted May 21, 2016 Yes all the link G4+ models can do modelled fuel equation Quote Link to comment Share on other sites More sharing options...
Scott Posted May 23, 2016 Report Share Posted May 23, 2016 Hi again, I've heard back from the engineering team, no problem with running a rotary engine on modelled fuel mode.Scott. Quote Link to comment Share on other sites More sharing options...
Explode64 Posted May 25, 2016 Author Report Share Posted May 25, 2016 I have had a look at both the FD plug in’s for the S6 and the S7/8 RX7 on PCLink. There seems to be a big difference in the number of inputs and outputs between the different series.With expansion connectors I have worked out that the S6 has8 Injector Drives4 Ignition Drives8 Auxiliary Outputs 9 User-configurable Analog Inputs/ Temp2 dedicated trigger inputs6 User-configurable Digital Inputs1 Channel closed loop knock control2 triggers And the S7/8 has8 Injector Drives8 Ignition Drives8 Auxiliary Outputs (Fan, Boost control, idle speed control, etc.)13 User-configurable Analog Inputs/ Temp2 dedicated trigger inputs10 User-configurable Digital Inputs1 Channel closed loop knock control2 triggersIs there a patch harness that allows the Link Rx7 Plug in for the S7/8 to be used in a 6 or am I best ot just go to a wire in ECU?

The S7-8 plug-in has received an update, and so has a lot more available on the expansion connectors.There is not patch harness available, so if you need more inputs and outputs than the S6 plug-in can provide then you would be best with a wire-in ECU.

Scott Posted May 26, 2016 Report Share Posted May 26, 2016 I'm not aware of any plans to update the S6 at this time. Best to go with the wire-in. Quote Link to comment Share on other sites More sharing options...
