I've got an S13 with a CA in it making a bit over 160kw at the moment using an SAFC V2.

I realise I'll only gain minimal power from the ability to control timing but I'm interested in getting hold of a proper engine management setup that will allow me to do my own tuning.

I'm looking at the Nistune and the E-Manage at present but am open to other ideas and am curious as to what other self-tuners are doing.

Cheers

i've been thinking about buying one of these kits for ages now

it will give you an accurate display of your afr's which is what you want to trim with your safc

i've played with both nistune and emanage. bin the emanage idea and use the nistune.

get yourself a wideband and some form of knock detection.

fine some open road and try not to blow shit up

Wideband is easy to come by, but what accurate, adjustable knock detection is available?

Ie. No point having a knock light if it's set to the wrong frequency for the car. And from what i've searched people have had trouble with the SAFC/ii etc knock detection?

^^^what he says and if you do get knock readings take it to a shop that has a Gizmo and get your readings checked against theirs, then you have a benchmark to work off.

and with th pfc you get two birds with one stone = ecu and knock reader. Note that its not the best one, it even has issues with noise and vibration affecting the readings, but as long as you get your readings checked [to confirm that they are real and not noise] then you can use it. Thats what I did, I had knock readings of up to 130 and then had this checked against a gizmo which confirmed it. I fixed the knock and got it checked again and was also confirmed. I can look at my knock readings on my pfc hand controller and be reasonably confident that they are a good indicator - I believe in the readings.

Nistune is fine but you would have to get something else to check knock levels if you're going to play with the timing so a second hand PFC would probably be more cost effective or better still a Link/Vipec with the knock control which would be more expensive (and you would be better to get your turbo upgraded with that money).

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
