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.

      From now on read it as minus 5 and minus 7 instead of dash, and you're correct...

      R32 GTR fuel gauge not working despite fixing fuel level sender

      By XoRoKu · Posted

      Opened up the cluster to inspect the gauge itself for signs of damage and it looks good. Got curious since that needle doesn't go back to a "neutral" position by itself (it stays in the same position when ignition is off. so I manually moved it to 1/2. Connected it back, turned on the ignition and the needle started moving up! Not sure what's up with that but before that the needle was way down below empty like fully south west. There's always a chance that the needle moved slightly the first time I tried and I didn't notice because of how slowly it moves and how far it was from the markings. I don't know if the current needle position is accurate so I'll fill it up and see where that brings it. I guess I'll try to adjust it manually if it doesn't get to F. Looks like the needle position is relative and not absolute? Thanks all for your help and patience!

      rb20de neo +t conversion - boost pressure sensor needed?

      By GTSBoy · Posted

      You're confusing two different responders and more than one issue. The stock Neo ECU boost sensor is used by the ECU for protection purposes. It is essentially only an overboost sensor. It is not used for determining engine load for fuelling or ignition purposes. That task falls solely to the AFM. Any aftermarket ECU that either has an onboard MAP sensor or a plug in one, will use the MAP sensor as the primary load sensor. Or I should perhaps say "can", rather than "will", because some of them have the option of using other primary load sensors. That MAP sensor is not for the same function as the stock Neo boost sensor. The reason I recommended against a plug and play ECU is that they are intended to run a particular engine and usually in the car that the particular engine came in. So, if you have a transplanted engine in a different car, with some parts of the original missing (such as the boost sensor, for example) and therefore likely non-standardness of the loom and its insertion into the car's loom, then it is very likely that you will run into the same problems with needing to fix up wiring to make it work that you would with the stock ECU. And, if doing so for the stock ECU is enough of an obstacle that you start considering a standalone plugin as a solution, it should become clear that the plugin is quite possibly not the solution you'd hope it to be. It would just lead to more of the same type of problem solving work to get it going. In the above paragraph and in my earlier post, the lack of the boost sensor is not critical. It was just used as an example of something that we knew you did not have right, such that the stock ECU would not work. I took that as an indicator of a reasonable probability that there were other related problems hiding there.

      I can think of two places in my city of <1.5million population that specialise in automotive instrument repairs.Unless you're out in the wilds of Quebec, you have 3 major Canadian and 3 major US cities within the same distance as the single nearest city to mine. Surely there is somewhere you could send it.

      I never cared for twins but whenever these conversations came up, I always presumed the higher number represented a larger turbo. Learn something new everyday.
