Anthony Parle Posted May 1, 2017 Report Share Posted May 1, 2017 I am using a G4+ Thunder for some R&D on slide throttles, doing some testing on the correct intake air velocity to acheive maximum cylinder fill. They are not for a road car just for research and so are controlled by two model servo's as such don't have a TPS. I do have a MAP sensors and RPM input. The testing only involves idle and full throttle. Iwas just goign to use a standard fuel and timing table using MAP & RPM as the axis's I assume that I can get the engine to run and just won't have acceleration enrichment, is that correct?

Adamw Posted May 2, 2017 Report Share Posted May 2, 2017 Hi Anthony,It should be fine. Usually it is preferable to have TPS with ITB's as the unstable MAP at idle is often not a good indicator of load, but since drivability is not the priority in this case it should run ok. If your MAP signal is reasonably steady you can even change the accel enrichment to reference MAP instead of TP. Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted May 2, 2017 Author Report Share Posted May 2, 2017 Hi Adam,Thanks for that, I am pretty sure I can get the signal stable as it all to do with the size of the header that connects all the throttles together, the bigger the header pipe they all pull from the less the possible fluctuation.Tony Quote Link to comment Share on other sites More sharing options...
