Okay. I have done little things with the help of everyone here. I got my widebands installed today and logged them and they look good. I have yet to put on my 102mm maf housing. I have yet to install fuel pump. I have yet to put in my 1000cc ev14 injectors. This is all i really have left.
I am thinking of throwing the maf housing on and tuning that in first. Problem is the housing i have is hitachi and the maf i have is bosch. Advise here would be good. I could switch to hitachi pretty easily getting a sensor wiring it in and flashing a hitachi m box since my tune is basically stock as is right now.
Then throwing fuel pump in. Then doing injectors.
I think this will be the best route. Although it will likely take a month for me to tune these simple things probably more.
From there i will follow the wiki's order of tuning.
Is this a good route to dive in??

Yes, Change only one variable at a time. Log now and not your fuel trims, and AFR under various loads. Nice third gear pulls. Then install the maf and tune until the ratios match again.
I would perform the conversion first in the stock hitachi housing to make sure its functioning properly, then scale for a larger housing.

105mm MAF housing? That is going to be a BITCH to tune. Why did you choose it?

Bigger is better yo! But seriously, if it can't be accomplished with a 90mm housing, it's time for a different sensor. HPX is wonderful. |

I got a Deal on The housing.
I see how it will be harder To find The value To scale The maf when you use a wayy bigger housing. But how would a hpx help? Is The flow To voltage ratio not like The stock sensor??
Should i ditch this housing or can i make it Work??

Got some logs today. 2nd gear and 3rd. Massive throttle cut. I will work this out first. n75 is unplugged im on waste gate pressure.

What good is a deal on a piece of equipment that is unusable. |

If i knew it was un usable i wouldnt have picked it up.
Your saying its unusable??

Started playing with KFMIRL and LDRXN. I set LDRXN high starting at 2000 rpm. I slowly added more and more to 50% and up on KFMIRL. This shifted my throttle cut to right. After one run at second gear some shit hit the fan. pulled these codes
17956 - Boost Pressure Regulation Valve (N75): Open Circuit
P1548 - 35-00 - -
16487 - Mass Air Flow Sensor (G70): Signal too High
P0103 - 35-10 - - - Intermittent
17535 - Fuel Trim: Bank 1 (Mult): System too Rich
P1127 - 35-00 - -
17537 - Fuel Trim: Bank 2 (Mult): System too Rich
P1129 - 35-00 - -
I have been watching my a/f ratio and knock after each run. I attached my log below.
Scared the shit out of me tho. Thought i blew the crap out of something but it was probably a backfire from it getting rich.

You need to learn to properly plan. Don't buy a MAF that is larger than you need, there are tradeoffs. |

What if i used a voltage divider and basically cut the output voltage in half from the maf. Kept the stock housing and everything. Then scale the maps for the maf down by 2??

That isn't the problem with large MAFs. You're losing a huge amount of dynamic range and low end flow sensitivity with the large MAF With stock MAF you'll just hit the output voltage limit of 5v. You're kinda not understanding how a MAF works :/ |

I am not talking about a large maf right now. If i want more range out of my maf sensor im suggesting cutting the ouput voltage in half with a resistor and scaling all the maps up by 2. Instead of using a bigger housing and scaling the maf that way. Would this work?

No, of course not. You'll hit the max voltage of 5v. Again, you don't really seem to understand how a MAF works. |
