Re: Hitting a wall at 4500rpm

Your best bet is to post this in the Nismotronic FB group:

Lots of experienced Nismotronic users there and John Kerr monitors it regularly.

Re: 615cc inj stock ecu

It could be an injector latency issue. At idle, the latency is a large portion of total injector pulse width.
When coolant temp reaches 175F, ECU goes into closed loop and short term fuel trim adds fuel.

Re: S14 internal coil distirbutor wiring for microsquirt/ms3

I found the diagrams you need in the '97 S14 FSM EC (ECCS) manual under the descriptions for trouble shooting DTC P1320 for the ignition signal and DTC P0340 for cam position sensor. Your pin numbers are correct and connect as follows: dist# -> destination 1 -> ecu pin #1 2 -> ground 3 -> ecu pin #4...

Be sure you have the latest version (3.25.0) before using the COP Wizard. If you are starting out with an S13 SR20DET base TCD, y...

Re: Injector signal voltage?

The injectors are powered straight from the battery through a fusible link, not through the ignition switch. The signal wire is open circuit until the ECU grounds it to complete the circuit and open the injector. With the volt meter across the injector contacts, you are looking at the voltage across...

Re: Nismotronic Standalone

The only small issue I see with nismotronic is that you have to use a S13 ecu, which brings up the price if you have an S14. But it seems that in the long run it's worth it with the added benefits. You don't need an S13 ECU with a KA24DE, unless you want to convert to COP. NismotronicSA will run a ...

Just to be clear: It supports the addition of a MAP sensor, IAT sensor, and boost solenoid, and wide band. Are the sensors used just for data logging, or are they fully functional in terms of map in...

That's not possible with a Nismotronic NEMU daughter board, There are stand-offs on the board to hold in positively. Maybe you have a basic 2-chip daughter board from J-K-Tuning?

Right, but he left off the part that says "Nistune requires a special hardware programmer to reprogram the code portion into the Nistune hardware". That's why it's not working for you.
