Warm start continues to work fine. In fact, the car seems to start far more quickly than with the oem injectors.

To prove my newbish ways, I haven't touch IPW adder as I have no clue what that is (or that it even existed).

I just installed the moddified Walbro 255lph HP unit and adjusted my latency's and scaling a little bit more. I am at work and did not bring in my laptop so I don't have the numbers handy. I will post more around lunch time.

Question, when I cruised around to adjust Mid Trims I forgot to update Mitsulogger with the scaling numbers I am using. Will this affect the Trim outputs numbers? I am going to spend a little bit more time to make sure the injectors are scaled properly, the numbers are very close now and I didn't want to find out I was way off base.

Thanks.

scaling 790?

 

As I recall, it is pretty close to that number. I started off in the low 700s and slowly worked my way up.

When you get a chance, post up your current latency values and the long term fuel trims.

 

Will do!

 

Nope, it is just used as an input to other calculations like calculated load and injector pulse width.

 

Figured I will post my scaling & latency:

6.120
3.624
2.280
1.560
1.032
.816
.648

93octane Scaling: 886
E85 Scaling: 585

 

Latency and Scaling for me (Stock Fuel Pressure Regulator with Walbro 255 LPH HP). I only run 93 Octane, no E85.

3.816
3.144
1.944
1.392
0.984
0.72
0.504

Scaling: 790

 

Do you want the long term fuel trims after a cruise? (Forgive the newbness again)

Dan

 

log your trims......it can take a while for the trims to settle out, just drive as much as you can and different road conditions (highway, city, etc) and idle.

See what your low, mid, and high work out to be..if they go over -5/+5 then you need to work on latency or scaling depending on which trim is off.

 

You guys should be able to use the latency and scaling parameters directly from the injector sheet.

 

As travman said, watch the LT fuel trims during daily driving. That's the info I'm interested in seeing and comparing to your latency and scaling values.

 

As far as latency, none of the values on the injector sheet match the voltages that the Evo requires entered into the ECU.

What I(we) did was create an Excel Spreadsheet that took the existing values and estimated the values the ECU needs.

Gotcha, so far using Mitsulogger, the values seem to float around -2, 0, +1 and rarely +2.

What I will do when I get home is disconnect the battery (to reset fuel trims right? I just learned that today) and go for a cruise and let you guys know what kind of feedback I get.

If you have an VIII then yes gotta disconnect the battery - the IX's reset on a flash.
