Turbo260Z Posted August 11, 2016 Share Posted August 11, 2016 Hello I have a set of 1986-87 RX-7 Turbo injectors. Part number: 195500-1370 550cc tan tops Low impedance If anyone knows the dead time (lag time) for these injectors I would greatly appreciate it. Need it for megasquirt for my l28ET Quote Link to comment Share on other sites More sharing options...
Chickenman Posted August 11, 2016 Share Posted August 11, 2016 (edited) 1.2 to 1.5 ms ( At 13.5 volts ) is good starting point according to RX7 forums. Edit: That seems pretty laggy to me. I would expect more in the range of 1.0 ms. I've also found documentation as low as .75 ms dead time with the Low Impedance 195500-1370's. Regardless, the IDT is just a starting point and has to be fine tuned per the ECU drivers. Might be better to post this up on the MS Forums. Someone there probably has an answer at their fingers tips. Edit: This seems to be quite helpful: http://www.msextra.com/forums/viewtopic.php?f=134&t=49918 Edited August 11, 2016 by Chickenman Quote Link to comment Share on other sites More sharing options...

Turbo260Z Posted August 12, 2016 Author Share Posted August 12, 2016 UPDATE: I have changed the dead time on my ms3 to 1.000ms from the previous 1.200ms, and it has significantly improved starting the car as sometimes it would take long cranks.
