Ian6 Posted March 7, 2019 Report Share Posted March 7, 2019 Hi, I wonder if some one could help me on this issue? I am experiencing a sudden flat spot while pressing the throttle various times consequently. it seems that the MAP sensor is not constantly responding quick enough. The log attached shows what is happening on the second throttle opening. Any help is really appreciated.Log 2019-03-7 1;23;09 pm.llg Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted March 7, 2019 Report Share Posted March 7, 2019 MAP is reactive to engine load, just because you put your foot down does not mean the engine is immediately loaded, without seeing your map file I would suggest you work on your Acell fueling, double check the acell load axis is set to TPS. As you can see in your log the engine is going very lean. Quote Link to comment Share on other sites More sharing options...
bsh Posted March 8, 2019 Report Share Posted March 8, 2019 Do you share the mapsensor vacumhose with something else? You are using the ecu internal map sensor? Quote Link to comment Share on other sites More sharing options...
Ian6 Posted March 8, 2019 Author Report Share Posted March 8, 2019 Hi, The log is on idle static however the accel load axis is set up on MAP, I will have a look and get back to you with an update. Thanks for the help. P.S. the onboard MAP sensor plumbed individually. Quote Link to comment Share on other sites More sharing options...

ClintBHP Posted March 8, 2019 Report Share Posted March 8, 2019 Man you need that ECU tuned, the fuel table is amazingly poor, no wonder you have a flat spot the table disappears down a cliff edge. Quote Link to comment Share on other sites More sharing options...

Adamw Posted March 8, 2019 Report Share Posted March 8, 2019 Also, accel hold needs to be set to 4 or 8 events. With it set to 2, only the first two cylinders will get accel enrichment. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted March 9, 2019 Report Share Posted March 9, 2019 If you log very slowly, it's always going to look crap ! And that table is pretty epic....seen some equally as bad from supposedly respected tuners too !! Quote Link to comment Share on other sites More sharing options...
