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)

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 (http://www.sr20forum.com/attachments/rom-ecu-tuning-file-exchange/403d1248456434-bin-opinions-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

as long as you don't use something too flamable :)

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