KA24DE-t throwing P0171 after retune

[Gmillz85]

Just got the kouki back from import intelligence, they retuned and dynoed her. Perfect a/f, smooth readings on the dyno (283rwhp, 250trq), a/f is perfect on The gauge and she runs great, but she threw a 171 tonight on my way home. Any suggestions? Z32 maf, im going to clean it when i get home but i domt know what gives.

Also, im getting a "click" from the rearend on acceleration. Cant tell if its the rearend itself or an axle. Suggestions on thus matter appreciated as well.

From what I can tell looks like your fully relying on the SAFC NEO for piggyback tuning. With SAFC and 550cc you would have to decrease a good amount on the fuel settings to work. This would also jump your timing up but looks like it was retarded about 3 degrees. I would recommend converting to a tuned S13 ECU and conversion harness for your tuning and retain the SAFC for minor adjustments only. Another good alternative would be to convert to S14 95 Zenki ECU and run Nistune to avoid having to do conversion harness. GL!

So am i damaging anything with this code? The a/f ratios are perfect and it runs 100%, idles smooth, smells rich. Something to worry about amd get fixed?
