raising the rev limit

**SgtMarshal** · 02-15-2015

would you mind looking at the maf worksheet to verify I did it right? the only part I am confused about is how to feather the afr so its smooth.

**NebTurboST5** · 02-15-2015

wow. this is a way nicer excel sheet then the one i used to use...ill have to play with it a bit. can you send me a copy of the virgin excel sheet and your log that you plugged into the sheet

**SgtMarshal** · 02-15-2015

you bet

**NebTurboST5** · 02-15-2015

you have an email.

**SgtMarshal** · 02-15-2015

so just save and upload the smoothed table

**NebTurboST5** · 02-15-2015

basically yeah

**SgtMarshal** · 02-17-2015

so I took another scan and forgot to log the o2. I worked up another spread sheet with the previous scans o2 readings, do you think that is fine, or go scan again with more attention to detail?

and I forgot to reset my fuel trims

**NebTurboST5** · 02-17-2015

the data will be worthless without reseting the trims. the O2 i dont think is such a big deal. definitely dont mix data from different scans it wont match up and will **** everything up. you need to reset trims and drive around town for at least 45 minutes before you start logging data for more changes.

do a few re starts too during the relearn of the fuel trims.

**SgtMarshal** · 02-17-2015

oh Ok I will try it again.

Did you see my last email Paul?

**NebTurboST5** · 02-23-2015

ive been out of town, ill take a look tonight.

**SgtMarshal** · 02-23-2015

I think I got the maf smoothed out, I'm going to work on the VE tomorrow and see if I can get some of my LTFT numbers closer to 0. I've been reading a tuning guide and found another tool called "Table Modifier" the scan data thingy, and think I have a pretty good understanding on how to bring in my LTFT's. it also has a timing adjustment where you click "SHAZAM" and it adds 1 degree of timing to every cell that doesn't have kr, and takes away 50% of timing in cells that have kr. I dont want to change my idle so do you think 2000 rpm is a good rpm to start from and go up from there?

**NebTurboST5** · 02-23-2015

do you understand the process for tuning the VE?

**SgtMarshal** · 02-23-2015

I think so, I'm going to read the guide again tomorrow to get the process fresh in my head but basically, disable the maf, and ease into the throttle while watching for kr and take a scan. I think it said to go 50% throttle and if there is no kr, take it to 75%, but no more. The application will make the adjustments. If I read it right it said I might have to make like 12 adjustments

Do not jus throw timing in because you have no kr. You need to concious of areas where theres light load to where you can add alot of timing and higher transitional high load boost areas.

I was going to start adding timing at like 3600 and go to 6000. I'm only at like 15 in most of those cells now. Going to go 1 degree at a time and scan, im hoping for 22 but 20 will be good too

Looks like you're past the subject of adjusting the rev limiter, but I'd like to share my 2 cents... if you raise the rev limiter, you won't get the benefits without raising the shift points also (like bill said). I'd like to add that you should have at least a few hundred RPM between your shift point and rev limiter. Otherwise you can possibly bounce off the rev limiter mid-shift.
