ECU part number you are using?

Do you have a speed signal showing in Nistune?

This is the 1994 Ecu the part number is either : 23710-94Y00 / 23710-94Y20. I going to check on speed sensing tomorrow. The whole reason for this question is I thought this was launch control....... but it seems that I just noticed a week ago in February that you just did a whole new overhaul of our boards...... so I'm trying to figure out if it's even worth it to address this issue..... if I have to send the board in, I'm going to use a 91-93 ecu instead. The 94 ecu has caused me alot of problems for the fact that you can't sync tunes from years. " 91-93" because the 94 ecu has pre obd2 features..... I was told something along those lines.......

There is no launch control (yet) for the later 94Y00 B13 SR20DE ECUs

There will be no changes to the Nissan firmware to affect the standard RPM limiter as such

The ECU is 64KB instead of 32KB address space so you cannot directly load tunes from earlier ECUs into it
