hmmm.... Now we are going back to the basics

Although the basics seem rather..well... basic! :laugh:

However, they are very important as they are the foundation of a good tune.

Some of the wild variations we are seeing in tuning numbers are in part due to the basics being incorrect.

You can not have a useful comparison unless comparing apples and apples.

All engine/turbo set ups do have different characteristics (so need different numbers to make them perform best)

But you cannot hope to see the differences unless your basic set-up is correct and consistent.

Anyway, enough from me.... back to looking at your tunes :banana:

When you think about it, its easier to just whack the car on the dyno do a few power runs, chuck in a extra couple of deg timing and trim the fuel.. 4 or 5 runs and walllaaa your done. $350 later the customer has more power and is happy with their tuner.

I have seen many many dodgy jobs make very very happy customers. its about the $$$

Back in the day i was one of those customers who were happy with his $200 tune.

bring it to me i will fix it.

Your timing in the mid range needs to be checked.

I'd like to see you just change the midrange timing.. my ECU is standard too :P

Tempted to get a PFC so it can be properly tuned for 98RON, but I'm probably wasting my time with a standard exhaust.

Exhaust + PFC + 10psi could be a good move when I have the money tho.

Your $200 tune story sounds like a friend of mine.. he had a basic "on/off" tune done on his EVO4 and the thing just dumped fuel on boost. We always joked about our fuel gauges going up when we followed him, and told him to get a proper tune as he was probably washing his bores down with raw fuel. Sure enough, the engine only lasted a short while and it was up for another rebuild.

      @joshuaho96 Hmm considering the drama you've seen/experienced, have you looked into getting a built complete long motor shipped from Australia?  Considering the AUD is basically monopoly money when compared to the USD, at a glance this seems like a good option?

      Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!

      I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).

      At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself

      I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.
