do you rewrite the values in the inj screen too add or remove fuel or do you do it in the inj correction screen for exsample

at 5000 rpm's i have a AFR mixture of 12.6 if i needed to add more fuel i would rewrite this value to 12.0 and that would be it for that load piont at that rpm ?????????

Does anyone know of a link for the fc datalogit (using it and its functions for the rb25det's)??????????

thanks agian mate.

i have red the instuction and i'm lost i have no base map like he talked about i have a fc datalogit for a skyline not a celica.

lots of things are bifferent. i understand that the method is the same but he is way to confusing in his way of teaching.

thanks for the link mate as with many more reading i should get it .

I dont use the excell formula to adjust it, will get close but it's not perfect, i just highlight the cell ( cells ) on and around the cells in the inj map and use the " - " and "+" buttons, press it five times and go for a squirt.

i generally use the correction values to see how far up or down it has to go and adjust the values on the map from there. When im getting it close i only adjust the cells on the map to fine tune it.

this is my inj map

    • Wrong question. There's no point in spending the rather large sum of cash and effort to add turbo, without taking it to the "sensible" limit of the motor itself. If you have to upgrade injectors, etc, then so be it. That is a tiny fraction of what it will cost you to turbo it.
    • Measure voltage at the starter solenoid terminal when the key is at start and it has clicked. If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself. If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison. <parts hoarder>No you cannot have it.</parts hoarder>
    • lights are on just the one click.  
    • Absolutely matters because, while a temperature change will eventually reach a sensor at the end of a static line, the response time is far far far too slow to be useful. Might as well not have a temp gauge at all.
    • When I was eyeing off the 370GT (after deciding I didn't want to spend 30-40k+ to relive my early 20s in an R33) I thought it'd be a good project to add a turbo to it. Now that I have a 370GT, and I've had a couple of chances to open it up, I'm pretty stunned by how much power it makes 🫠 Honestly, the way the VVEL opens it up, it almost feels like there's a little turbo tucked away in there somewhere. It's like Nissan looked at VTEC and said "hold my beer" 😁 Has anyone thrown a turbo into their 370Z or 370GT? Is there a conservative boost level you can run without having to upgrade the fuel system, or are bigger injectors and a bigger pump a given?
