I've got a weird problem.

When i am starting out from a stop (kind of slowly) when i depress the throttle enough to go from using only the primary throttle bore. To just starting to open the secondary throttle bores my A/F goes from rich to dead lean then back to rich again. And this all is in the transition faze of just starting to open the secondary throttle plates.


At first i thought "ok i need a tps sensor" but when i watched the values the commander. There is no drastic jumps in the voltage readings. In either the narrow or wide angle tps readings.


Dose any one else have any ideas i can trace down to eliminate possible solutions???

Any help would be of value

Thanks

Adam





PS its not in the fuel map.

 

DATALOGIT Settings 5 might be wrong for your injectors, unless someone hosed you acceleration inj SETTING 2 map.

 

Well i just had it tuned by Jason at RX7 Store. And i know he changed some injector settings.

The more i mess with this car, the more it seems a datalogit is a must.


Damn,

Thanks for the reply. I guess i will haft to wait a few weeks till he gets back in town.

 

Now that you mention it.


Isn’t this the time where the secondary injectors come on line??

 

Settings 5 is where you control all the injector settings.

I would have Jason fit it since he made the changes.
