Re: RB25DET NEO Ignition map tuning question

The beta tune is what is currently being run but he took out fuel to make it 11.2: AFR, the file didn't save however. Would it make more power if the afr on high end were leaner? He said 11.2 is leanest I can go on 93 octane fuel, but would 12 AFR be ideal? The knock timing maps and fuel maps were n...

Re: RB25DET NEO Ignition map tuning question

Hello Matt, Attached is a graph of the dyno results and the current tune, I didn't use the updated map you attached because there is no knock maps on that one (all the values are 0), I also don't think knock analysis works on this ecu, is this the case with the stagea ecu, does it not analyze knock?...

RB25DET NEO Ignition map tuning question

Hey guys, I have an rb25det NEO engine with 620cc injectors and HE351CW turbo. The car is running great with a rough tune but I want to take it to a local tuner to tune, Alamo Autosports in Texas, on a dyno. He has never used nistune before but is familiar with a lot of standalone systems. He is tel...

Re: Rb25 neo runs lean in 4th and 5th gear light load

Hi Matt, I have the car running pretty well in light load and cruise. I think I have the K constant at the ball park where I need to be 385. I redid the k constant and injector resize and found the ttmin and max values were off at first and after corrected the car ran better. Also I fixed a leaking ...

Rb25 neo runs lean in 4th and 5th gear light load

Hello, I have the car running fairly well at idle and I'm trying to adjust K constant enough to drive it to the dyno after upgrading the turbo and injectors. I am only slowly driving it down the road not going above 2500rpms and it drives fine from 1st to 3rd gear but as soon as in to 4th i start se...

Re: Rb25 neo wont start after maf and injector change

I had the vehicle running properly before doing the upgrade, literally all I changed was the MAF, injectors, and turbo/hotside. Even with the stock map and fuel pressure at 60 psi it ran. I checked with a multimeter and all injectors had 12v. At this point I think I can only revert back to the origi...

Re: Rb25 neo wont start after maf and injector change

After pulling the fuel rail off we realized that the first three injectors werent firing at all, and the last 3 were very weak. Fuel pressure was at 43psi at this point. I checked with a node light, and all injectors are getting a pulse, but extremely weak. At this point we were using a battery that...

Re: Rb25 neo wont start after maf and injector change

Thanks for the help Matt. I tried the new bin file and still having the same issue. Turns over, seems to catch for a second and then dies again. Is is possible the computer is fried? Originally when I first started messing with nistune, we had base fuel pressure at 60 psi, without touching the stock...

Re: Rb25 neo wont start after maf and injector change

So replaced the spark plugs and CST, nistune still seeing -49 to 200 degrees on the CST, so left it unplugged. No change, still not starting or idling. I am posting a bin of the most recent attempts to get it to start. After looking at the injector latency on the seimans website, it shows the ON tim...

Re: Rb25 neo wont start after maf and injector change

Matt when yous say to post my map, thats the Bin file correct? I am 100% sure I didnt check the cranking table box when I did the resize. After messing with it over the weekend, I realized my K constant was retardedly high, like 2200.. It flooded the engine after multiple attempts at cranking, and f...

Rb25 neo wont start after maf and injector change

hello, I finally got the car put together and was hoping to get it running to baby it to the tuner. As of right now I used the drop down list for the AFM change to the Z32 maf, and went from 370cc to 630cc injectors. Changed the injector latency to 1.14ms as well. Car doesnt want to even catch, no s...
