Still new to Efilive

1999 Firebird, new engine, no wideband. where do I start?

[joecar]

You will need a wideband:

Do you have FlashScan V2...? If so then get a wideband that outputs the AFR/Lambda/ERQ in serial format.


Units:

In tunetool go Edit->Properties and set units to g*K/kPa and EQ (if you really need AFR, we can make a cheatsheet).


Starting File:

Start with a 2002 Camaro/Firebird file (OS 12212156) with the same transmission segment as your 1999 Firebird has.

There maybe some tables you need to copy, but at this point I don't think it matters.

Maybe you can obtain a pre-made file that matches your mods as a starting point.

Then:
- recalculate/edit the IFR table, edit/copy the other injector tables,
- increase your VE table by some percentage,
- set up the file for AutoVE (SD/MAF-less, OL, no LTFT, no STFT);

You may or may not decide to configure the PE table.

Flash this in (full flash)... then:
- start engine, see that it runs;
- and do AutoVE for low/medium load,
- do idle/RAFIG tune;
i.e. get it running ok at low/medium load/idle.

Make sure everything is mechanically sound, no leaks (air, exhuast, coolant), no noises.


Swap Files:

Then swap to COS5/02020005... you full flash this in, and then you cal-only flash from the 12212156 file...
you will need to edit some of the Axxxx tables to set in-range values.

You will have to read thru these COS5 topics:
showthread.php?t=2599 (http://forum.efilive.com/showthread.php?t=2599)
showthread.php?t=2270 (http://forum.efilive.com/showthread.php?t=2270)

In B3647 disable semi-open loop (change any cells that are EQ 1.00 to either 1.01 or 0.99).


Boost:

Set B3647 OL Fuel table high load columns sufficiently rich for boost;
Set the B5913/B5914 spark timing tables suitably for boost.

You may or may not decide to configure the PE table.

Now do another low/medium load AutoVE iteration to verify everything is ok.

Copy the 105kPa column of Main VE table to Boost VE table, edit the rest of the Boost VE table to make sense; now do AutoVE for high load... check your BEN... if it deviates too far from 1.00 then manually adjust the Boost VE table and try again... keep an eye on KR.


Objectives:

After you got it running/idling in OLSD, determine what you want to do, run with MAF and/or CL, or not, and take appropriate steps.

There's more to it than a 1 page reply... :)

holdencrazy is down, so im waiting

[mr.prick]

stock '02 fbody.tuns

[pdasterly]

thanks

[pdasterly]

whats a good mobile wideband

[Tordne]

Holden Crazy is back up. Messed up a firewall rule after some changes :(

Mobile wideband wise, I think the Innovate LM-2 would probably be about the most popular. There is a single and dual channel/sensor option also. This device is supported for serial input to the FlashScan V2.

[mr.prick]

You could make any WBO2 "portable".
I have my LC-1 powered from the rear NBO2 harness.
If I want to remove it all I have to do is unplug it from the harness and V2
then pull wires out from under the carpet. :hihi:

ngk afx, and get the ntk sensor. alot more accurate then the crappy bosh injectors. IMO

While I agree that that sensor is more accurate than the sea of LSU's and it is certainly more 'hardened' (I had one last 2 years and hundreds of setups), especially against leaded fuel, the AFX has only an analog output. You lose what is in my mind one of the better features; the serial link for the WB to hand off data to EFIL.

[z28ls1818]

IMO I think accuracy should be the main priority. I had my car tuned a couple of years ago with an lc1 and it put down like 371 rwhp. Then it was tuned by the same guy with an ngk afx with the ntk sensor and it put down 389 rwhp. Mind you that besides cold start tuning and modifying of the ve table cause of the new readings. Nothing else was changed.

Even the same dyno on different days may not read totally consistently. It also says that the first time around, the tuner didn't take the time to find out what made peak. If he was looking for that, he would have found it regardless of AFR and the sensor. 18rwhp is a LARGE gain and doesn't come from being 0.2-0.3 off on AFR; it must be well over a point for an N/A setup. That's huge, and if the dyno were repeatable then it means you were way off the first time. Your tuner should have noticed something was awry. With the AFX and an analog input, because of the possibility of ground offset vs. the straight serial connection, you still are absolutely not guaranteed the most accurate result. It's just something to consider.

Agreed.
IMO LC-1s suck ass natz lol. I always here that they are way off and are always burning out.
