Yes, here's a scenario.

Say your original tune by Tuner A has been done, with the wrong injector data, wrong sensor scaling, base timing not synced properly. Tuner B then hops on, fixes up the cock ups and now realises the fuel table & timing tables are pretty much invalid.

Easier for them to copy and paste a known working tune from a similar car they've done in the past with similar mods, then tune/calibrate accordingly 

Yep that makes a lot of sense, actually I was reading reviews a few minutes ago of this exact same scenario that you mentioned. Now, I wonder if they will do a copy and paste tune, doubt it lol. Less money that way for them.

Why? They will still charge you for a full tune.

Really even though they save a ton of time with the copy paste it's still the same price as a full tune? I thought it was a time thing where the more time they spend the more money they charge, now if the adjustments take the same amount of time then that makes sense to me, or am I missing something?

Oh you sweet summer child. It might be easier to look at this from the Euro scene, in this case a Golf Gti. A super quick google...

$1,175  for a "stage 1" tune.

Oh it's on sale! $800 for a "stage 1" tune. 

So, in these instances the car never sees the dyno, no mechanic ever sees the car, no tuner touches the car. You hand over a large sum of money and you get a copy paste flash tune uploaded to your ecu. 

So much of the tuning industry is like this. 

Why would a tuner, turn down the opportunity to extract a minimum of $1,000 from you? It's an easier pill to swallow for the average customer when they sell it as a "full tune". Oh I'm sure they'll happily bill you for more if you want something special done on top, but the price of admission will always be for a "full tune". 

I really hate to be so cynical about this but it's reality. The obvious solution is to tune the car yourself.

But a Skyline is not a OEM hardware flash tune. Skyline mods pretty much START at Stage .. 8 or something like that.

To "fix up" a tune you have to first familiarize yourself with WTF is going on. Any tuner will realistically have a look and see if the baseline actually makes sense. If it does, then yes of course they will use that as a base and spend time tweaking and modifying it. If it's way too far from what they are used to they will start from scratch, but treating the current tune like a baseline is as good a place as any to start as long as it makes sense to do so.

However it is a CYA technique. They do not expect that the tune to be 30 seconds of work away from being perfect, and they have a paying customer with a complaint that they very much want to resolve. To do that properly they quote high and will go over everything to make the thing work as well as possible.

It would be crazy for them to assume that they can make a fast tweak to fix a tune made by someone else on a car they don't know. It could also not be a software problem as well.

Hence they rather copy / paste a tune with similar mods from a previous car as a base, not to mention all the tables are scaled how the tuner likes it. And in the odd event, the car has like for like mods as the file they have on hand, even better!

Means less work.

I once did 2x S15s with GTX2867R turbos, same 980cc injectors, one had Procams & broken VTC, one had Poncams and working VTC. Did I start from scratch? hell no.

Ah, I thought as much lol. Me tuning the car myself would be a disaster, I'll just pay the 1k+ 🤣

That makes sense.

    • 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?
