Hello,
Friday night ran newly acquired car with 3.3T AWD five times down the track.
Car has basically the JB4 450HP Kit with Lozic TCU and snorkles.
Ran roughly an E30 mixture of fuel and ethanol.
In every one of the logs (One Map 2, Four Map 3) in Ign #5 there was a bizarre reading of "180.7" for two to three successive RPM readings (ex. 6097, 6114, 5254 of 5th gear).
In the 3rd and 4th run Ign #6 spiked to 21.0 and 19.5 respectively at the same time as the 180.7 in #5 Ign.
Both of those with Ign #6 spikes at the same time were early in the run at the starting line loading up the boost.
Car ran ok, range of 12.08 to 12.26 in the 113 to 115 mph range.
Has anyone experienced this or know what the cause would be ?
Any ideas, please assist.
Thanks, Jeff
 
We would need to see the log / graph.
 
Change Ign2-6 logging for relative and not absolute value.
Ign5-6 180.7 reading means that JB4 doesn't read them correctly.
Check connections and JB4 firmware.
 
Those are decent times. So the 18.0+ in the other ign would mean extreme ign timing corrections due to octane limit or is it still the connections?
