Well as title says just got my 32 dyno'd for the first time other day at unigroup. really didnt know what to expect car is fairly stock bar: exhaust,fmic,pod,spitfires,cai,ss manifold,dump/front pipe and highflow cat. Now i was told car is running lean and as you can see there is a noticable power drop just after hitting 5500. I was told it can either be a air leak or faulty afm. any ideas at what else i should be looking at to rectify this and improve my ride

cheers

Graph looks pretty normal to me

Car looks pretty rich to me and seeing as you running standard ecu it seems fine. Air:fuel ratio going down to 10afr.

When car's are tuned they usually sit dead straight on 11.5-12.5afr (depending on how lean you want the tune to be)

Have a look on the stickie rb20 turbo upgrades ( http://www.skylinesaustralia.com/forums/Rb...no-t103095.html ) to compare dyno runs.

You sure you weren't told it's running rich?

That's incredibly rich. Heaps more torque to be gained by leaning that out. It's fine though. Not dangerous or anything. You're just wasting fuel and potential power. :D (And giving your plugs a hard time)

You have a stock ECU and have changed the exhaust and intake system. It's gone into a region of the fuel map which it wasn't designed to when it had stock parts on it. Time for a remap. ;)

thanks for the input guys. yes my mistake i meant rich. and yes it does use more fuel than normal. have been looking at a toshi remap for a bit now. just want to get some few parts here and there, then book him in, as im not looking for huge gains from this car.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
