Basically I put a power FC in my 34 GTR just to see if it works...and it does. When I put the standard computer back in the keys were now unsynced and I can't start the car, so I had to put the FC back in.

Nissan here is useless and don't know how to recode the keys and I am 1000k's away from somewhere to tune the FC. I will get it tuned..probably Marchish.

I have been told the main difference btween a factory ECU tune and a FC base map is mostly the timing as the fuel map is similar.

Attached is screens from my FC. My car is a basic pod/exhaust car so can anyone compare their maps if they have a similar state of mods and see if there is anything I can change?

as don data has said, the base map should be fine if you are normal and dont trash it and keep it on stock boost

using a "touched up" tune is just going to give you a false sense of "tuned" and youll trash it

putting the engine at risk and everything else. if it was me, stick with the base map, run low boost and get it done properly

status wouldnt suggest it if it wasnt safe paulr33....i think he knows what he is talking bout.. and would be more safe then any base map crap

This. That's a good offer from status. I believe that the Status tune will pretty much be the base map with far less aggressive timing, since timing is the thing that makes an untuned PFC unsafe.

no, they screw into a bung like the factory narrowband sensor. they can directly replace the stock one and still work with the factory ECU. however if you want to run a wideband o2 in the first place, there's a good chance you don't even use the factory ECU anymore...

stear clear of innovate. old ones are good but they're newer stuff is very unreliable and buggy.

Yeah my LC-1 has a recurring bug, but i 'downgraded' to the old firmware and works like a treat.

having known this before i would've gone for a AEM UEGO, but at the end of the day, i've got a wideband that works fine, just took a little more fuckin around.

Sorry. I'm sort of confused. Wouldn't it be waaaaay easier to have a device to check air fuel ratio's without changing the factory setup which may affect the way it is tuned to start with. I always see tuners use simple ones you clip to the tail pipe and do an on the spot reading. Wouldn't a gte computer use the sensors for tuning. Why would I replace one just for a stand alone meter??

standard o2 sensor is only used during light load cruising at a constant throttle. with all aftermarket computers you can and should turn it off completely whilst tuning anyway (which is when you'd be using a wideband) so its very easy to use it in the standard spot. tailpipe clips are easier for tuners because its quicker and the dynos setup that way, on the road its easier in the standard spot.

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
