Misihimoto Intake Tables for Rom Raider

[efactor84]

Anyone have tables I could use to dial my trims for the Mishimoto Intake? I got a CEL for p2097 and p219a.Both CEL pretains to fuel trim rich and afr imbalance. I'm running OFT and OFH Stage 2 UEL tune and I currently use 93oct. Thanks.

Thats strange, help a guy with one of those intakes a while back and it was pretty close to stock scaling.

think you may have other issues like intake/exhaust leaks, or dirty maf sensor ect.

When you say pretty close to stock scaling you made no changes? I checked the difference on the MAF Scaling between OFT and the stock any they are both different. Worst case if Shiv doesn't resolve the bug issue I'm having with the MAF Voltage and the IAM for CAL ID D00D, I'm reverting back to stock airbox. My next plan on action is to check the exhaust leaks when I installed the headers and checked to see if the o2 are tighten in the morning.

Update: Now I'm seeing my LTFT jumping +10-14 when I hit the gas in close loop. I switched tunes and same result. So its obvious I have a leak or something loose somewhere. Keep you all updated.

I'm going to inspect tomorrow to see if there are any leaks using the cloth and soap/water method.

The front o2 sensor was loose. I've checked under to see if there were any leaky gaskets. I didn't find any leaks, when I was using the soap/water method or unusual noise. My fuel trims were between -.78 to +3.24. Later, I found the rattle noise coming from both the o2 sensor's rings. This helped answer my question and hope this will help others, who experience this.

I had no such issues with mine. Which begs the question, is it the new style Mishimoto Intake?

No, it's the one that requries to remove your bumper; it would look like Perrin's setup. My trims came down between +8 and +14 everytime I hit the gas. That's when I found my main issue was just a loose o2 sensor causing my afr to be imbalance and running rich.

Thank you, was just curious. I too have the original remove the bumper option. Sure it's a pain the ass to remove a bumper for an air filter but seems like I'm always taking it off and putting it on anyway.

My trims so far, since the fix hasn't changed. I don't know if I need to do any adjustments. My LTFT is at +1.56 to -.78, sometimes it will be at +3.98 when I accelerate and it corrects itself to +1.56. I haven't done any tuning yet and I don't think I need to. I'm happy its running the way it should. My fuel mileage went up by 20 miles more before I hit the halfway mark at 140mi instead of 120mi. I'm continuing using Shell 93OCT, which seems to help calm down the cricket noise; its not eliminated completely. The rough idles hardly hit that many times like before, maybe once in a blue moon I might get it during the week.
