1st log after my tune plz critique!

[shadyst]

I dont have WB tuner yet so havent been able to change afr if needed.

[5.7ute]

Can you post up your tune file as well? Also a list of mods.

mods are headers, 3500 stall, 3.46 gears, slp airbox, 30# svo inj.new OS.

You might want to set these back to stock:

Engine Calibration.Abuse Management
{B1201} Abuse Management (in Gear) Upper RPM Threshold, changed from "2000" to "0".
{B1202} Abuse Management (in Gear) Lower RPM Threshold, changed from "1500" to "0".
{B1203} Abuse Management (in P/N) Upper RPM Threshold, changed from "2000" to "0".
{B1204} Abuse Management (in P/N) Lower RPM Threshold, changed from "1500" to "0".
{B1205} Abuse Management TPS Upper Threshold, changed from "5" to "0".
{B1206} Abuse Management TPS Lower Threshold, changed from "3" to "0".

{B1208} Abuse Management Commanded Fuel, changed from "12.188" to "0.000".

Are you running the engine rich on purpose? Your commanded fuel table in the cruise/low load areas is set way too rich as is PE.

[joecar]

Set D0935-D0937 to less than D0920-D0922.

no im not trying to make it rich, like I said I dont have the WB so I havent touched my afr to my knowledge. changed the pe based on rpm to 12.6 i dont know where the cruise/low is at to change that. these are different from my original tune from before I upgraded the OS so thanks for noticing what I have over looked!

LTFT's are inactive even tho CL is enabled in calibration.

MAF seems to be limiting at 206 g/s... is this due to elevation...?

Is this a 1999 Camaro...?

[joecar]

What 5.7ute said, your PE table is edited to way rich at AFR 11.7... you're not boosted, so 12.6 should be sufficiently rich.

yes it is a 1999 camaro and the elevation is around 4500-5k

Set D1108-D1110 to 0.3 seconds.

Set D0701-D0703 to start rising at zero (i.e.no flat spot), and bump the rest of the curve up 10%.

If your shifts are too harsh, then add torque reduction back in to D0801-D0803.

You have a 160°F thermostat...?

[joecar]

Car should run stronger... put the engine and trans calibrations back to stock (including the engine diagnostic and trans diagnostic) and see how it runs then.

[joecar]

Oh, LTFT's are zero because of O2 activity DTC... engine is running too cold.

[joecar]

Mick, what other things do you see (I have to commute home now)...? :wave:

changed thank you for the info! and yes it has 160 stat in it, i didnt let it get warm i just started it drove down the road, i didnt know what to do my 1st log so was kinda winging it.

[5.7ute]

I was looking at changing the low load/cruise areas to stoich from 60degC up in B3605 & B4206 to enable. But as you said, the DTC is preventing closed loop.
A log with the o2 voltages would be good.

so im a lil confused on the base curve did u want me to start from 0 and raise 10% from there or use whats there already and add 10 % to those numbers?

[shadyst]

Car should run stronger... put the engine and trans calibrations back to stock (including the engine diagnostic and trans diagnostic) and see how it runs then.

if I change those back to stock then that puts my injectors back to stock and im running the 30# svo. and that changes the tranny base shift that u told me to change by 10% back to stock......that what I should do basically puts the whole tune back to stock....I must not know what Im doin tune wise if I have to take it all back to stock lol

[5.7ute]

I believe he wants you to do a comparison before & after his changes, not completely back to stock.

ah gotcha, sry im im a lil slow on the uptake still a newbie lol.....so whats the proper steps i should do to make sure its a correct log? since i just started it up and loged goin down the road and back.

[5.7ute]

Since we have a limit of how many channels we can log, you need to set up a plan of what you want to work on first.
Joe is the trans guru on here & will be able to help you sort that side out. I have had limited experience with the autos so I try to stay out of that side of things.
One thing you will need to log is the o2 voltages along with an airmass pid,ECT,IAT RPM,MAP,commanded AFR,KR & VSS to get started. STFT & LTFT can be logged as well if there is enough channels available. A wideband would be better but these will help you get things into line. Also maf frequency.

[joecar]

Yes, leave the new injector values and the new axle gear ratio as is.

No worries, we're all newbies at some time or other... and we're all still learning a lot, we haven't stopped... if you don't know then ask (otherwise you won't ever know)... :D



so im a lil confused on the base curve did u want me to start from 0 and raise 10% from there or use whats there already and add 10 % to those numbers?See attached howto diagram.

Good idea Mick...

shadyst (http://forum.efilive.com/member.php?u=9121), go ahead and log HO2S11 and HO2S21 and what 5.7ute(Mick) said...

On the PIDs tab, when selecting pids keep an eye on the channel count... keep it at 24 or less (i.e. 4 packets) for fastest sampling rate.

Mick, feel free to add your comments to any part of this...:cheers:

[joecar]

Delete DYNAIR, GEAR, TCCMODE.

Add HO2S11, HO2S21, LONGFT1, LONGFT2.

[joecar]

In MAF mode, the trans shift adaption may or may not override the base pressure shift tables...

but when you go MAF-less (e.g. for AutoVE procedure) then the presence of the MAF DTC codes will probably disable shift adaption... this is where you have to make sure that the VE table allows the PCM to compute the sufficient engine torque to command sufficient trans pressure... we can help it along by bumping up those 3 tables.

I worded it non-committal because the various PCM's and OS's may behave differently.
