Bin Opinions

Octave236 · 07-24-2009, 01:34 PM

Ok so here goes. I'm wanting a safe Bin. I have one that I was using before my motor gave out on me. I dunno why as it was opened up and checked out before using it but less than a week later it developed rod knock and spun the bearing at 7 psi. I have been told that detonating can reslut in rod knock because it puts excess stress on the bearings. Although I suspect it could be old injectors being the culprit, I'm going to flow test them to check that out. I am going to post the Bin I was using. The setup is/was DE-T N60 maf 440cc supra top feed injectors at 4 bar. Now with using the K value calculation I should have been around 19000 but looking at my wideband and tweaking it at idle and cruise it was setup at 25000 which if I'm mistaken is a higher number than 370cc at 4bar with an N60 maf (22392) to be exact. So this was one flag me and calum didn't like. Just made no sense really. But I was gonna get it on a dyno and check it all out but it died before that (1 year ago). I have found out since then that the supra injectors run at a different latency than the nissan injectors too. As of just a few days ago I have been getting back into knowing the Calumsult RT ecu and Tuning. I started comparing fuel maps and timing maps and mine is way different than any Bin shared here in the calumsult section. So with this in mind I'd like to re-think my base Map/bin. I have DL a few bins I'm intested in. And I will share them here along with My Bin. I'd like someone who has time to kinda look at them and let me know what they think is the safer tune. I also have an N62 MAF now but I'm continplating not using it till I know everything is working right as I know the N60 maf works great. Also the setup now is with 8.5:1 pistons and a T3/T4 60 trim turbo .84 ar turbine housing. It was 9.5 with a bigger trubine housing (very laggy)

bump, maybe calum will get back into town today and see this

so I got a lil scientific and built a injector flow bench. I wanted to make sure it's not my injectors foiling the whole thing up. Set it up at 3bar they flowed 438cc giv or take a cc. Then I set it up at 4 bar and they flowed at 504cc give or take a cc. This is really close to how they are supposed to flow and alll 4 flow really really close to the same. at least in the 1% range( which is great). So it has to be something with the Map. Once it's running I'm gonna try a different bin instead of my my Ben - 440-4BAR-N60 MAF(2).bin . Still though I'd like to try a safe bin, timeing and fuel map wise, so which of these seems the safest. I'm not used to looking at fuel maps. I know what timeing maps tell you but not sure about fuel.

if your intrested this is my DIY flow bench lol

^^ is that safe?? i like it!!lol

as long as you don't use something too flamable

thats not gasoline. it's still somewhat flamable though just not as much.

just gonna bump this for any of you tunning gurus out there

bump for good info
