What is req'd to update 2008 Vette to 2010 ecm? 2008 ecm is pooched and would rather update than replace with same.
:cheers:
Numbers less than 1 are richer because longer pulse widths are commanded to make up for the lower flow rate the ecm computes the injectors at.
I posted before realizing the op was using wet system. :doh:
For extra fuel with nos when iat resistor is used, set inj flow rate vs iat. I used .86 at 50C> [ used a resistor that read 60 C in the scanner]
This is for a dry setup
Ha, never considered that.
Try putting rpm cutoff to 2000 in all gears - worked for me. Loaded that tune in their parking lot.
whose car is that ?? :D
how is he not seizing the rotors?
aha! :cheers:
I use commanded lambda and lambda error in the table and histogram. What is the advantage of User defined vs listed pid other than a one time shorter equation entered? :confused:
:
(([AUX.20122]-[PID.68])/[PID.68])*100 ..........maybe
or ((AUX.20122]-1/[PID.68])/1/[PID.68])*100
post if this doesn't work
:cheers:
nice low octane table
12* @ 2400 rpm ramping up to 18* @ 6000 rpm should be close enough to start tuning from.
Wrong curve for a pd. Reverse it - as in 12* low rpm 18* high
:cheers:
removed
oops - guess I misread
:cheers:
My comment was to show that the afx just reads lambda [at stoich or elsewhere] and then converts the display to afr.
You haven't explained how you are testing to show this is not the case.
Are you sure? I have several AFX's and no matter what fuel, they show around 14.5 in closed loop.
I ran a similar cam and had alot more midrange timing.
That may cause rotor seizure!
Is it possible to upgrade to a newer style?
Posting came across poorly from my long frustration of misinformation on this topic.
The site I posted has some good basic info with a qualifying formula.
I don't place much on anecdotal info but...
Air implosion causing pin holes in liners has several cavitation causes[vibration, coolant properties, sonic waves] but none are identified as thermostat removal and water speed increase.
Heating...
There is good info at this site: www.arrowheadradiator.com
Insults were not intended, just frustration at no search for more info before responding.
