Thread: UPDATED n/a sr20de bin for n60 maf

Im had some time lateley use my wideband and play with my tune some. Nice improvement over the last.

Check it out and tell me what you think. feedback welcome!

Just upgraded to the N60 on my DE, used your 1st version bin. Works nice with the S4s, looking forward to your 2nd version on a wideband tune. Just noticed, you leaned it out at the upper rpm. What was your AFR at WOT with the new tune?

If irc its 12.4-12.7 mid to upper 12's. Previously it was very rich at high rpm, but still seemed to haul the mail.. damn butt dyno lol. Fuel mileage sufferd so. This new tune is better so far. Need to do more driving!
Do you have a wideband blusteelsr20?

What's the engine specs that you're using with this bin ?
Is it 9.5:1 or a 10:1 motor ?
Is it obd2( from the b14) or obd 1 ?

Its just a 9.5:1 USDM DE. This is my b14 200sx we are talking about but it has a stepdown harness for obd1.

Just bought one recently for the DE, need to install ASAP to see where I'm at. My VE B13 has one and it helped a ton so I need to get on it and get 'er done for the DE. I see where you took out fuel @ WOT and below now I know why. The Calum RT/Tunerpro will iron things out once the wideband goes in. You did some work on the timing map with the new tune?

Yes with this new tune i removed lots of fuel in the upper rpms and added about 4 deg to the whole timing map Beware of pinging! Im good so far with only 89 octane.

I now have another updated version. Same as this, i just changed the tp scaling for the fuel map. Im getting awesome results now. Great gas milage too boot! I'll post it tonight if i can remember.

Not trying to thread jack but how do you guys think this will work out with a 10:1 high port motor. I'm thinking of trying this as a base then playing around with it some more when i do get a chance. I'll be using it in a nistune ecu. My engine has the following mods. Pulsar gtir exhaust cam, 3 inch CAI, Z32 AFM(soon to be installed), factory tubular headers, 21/2 inch exhaust(crush bent) advanced timing to 17* and throttle body coolant bypass.

It should work well with your setup. Give it a try! You might want to start off at 15deg (thats were mine is at) and work up to 17.. The timing is already fairly advanced on the timing map. Use Caution!

Looking forward to the new version, noticed that the fuel TP scale was not the same from the 1st version to the 2nd. 2nd version feels better than the 1st from driving impressions so the 3rd one should be golden. I'm running a 10:1 highport on 91 octane @ 15 degrees w/SSAC, 2.5 exhaust, S4s, 3" CAI if this helps anyone.
