Just installed COS5 - Questions

[jermstyle]

First off - This is pretty cool. When I first bought my car I was looking at engine management systems for some of the features that we now have with COS5.

I flashed the computer last night with COS5 and then uploaded my adjusted configurations tonight. The car started up and runs - but it's really choppy and stumbles a bit.

I assume that it needs to driven so it can 're-learn'. Is that the case or is something else at play? I followed the documented instructions exactly and researched every custom table on the forum so I'm pretty sure that it's configured correctly - But I could have missed something.

Also, after installing the new OS my change oil light is randomly flashing at me and some of the other dash lights will blink a few times when I start the car. Is this expected?

Right now it's in valet mode because I need to drop it off to have some work done. That works flawlessly! I'll ultimately wire it up to my nitrous system so I can pull timing on the fly.

You need to adjust {B3647} "Commanded Fuel vs RPM (Normal) for starter's. It would be choppy when your commanding 10's AFR for your idle. Read the Custom OS upgrade tutorial.

jermstyle, welcome to the forum...:cheers:

Get these into range:

EFILive Custom Calibrations
{A0001} Forced Octane Scaler Percentage, was out of range when loaded.
{A0002} Octane Scaler Limiter, was out of range when loaded.
{A0004} MAP Disable TPS VE Table, was out of range when loaded.
{A0005} RPM Disable TPS VE Table, was out of range when loaded.
{A0006} TPS Disable TPS VE Table, was out of range when loaded.
{A0018} N20 Monitor VE Multiplier Table MAP Enable, was out of range when loaded.
{A0015} N20 Monitor VE Multiplier, contained one or more out of range values when loaded.
{A0016} N20 Monitor Timing Table, contained one or more out of range values when loaded.Questions:
1. does B4001 match your injectors (check using spreadsheet)...?
2. do you have the unreferenced-returnless fuel pressure regulator...?
3. is your B0101 dialed in using wideband/AutoVE...?
4. how close in agreement is the wideband AFR compared to commanded AFR (B3647, or during PE the richer of B3647|B3618)...?

Little background. I installed the heads/cam and other parts on my car and took it to MTI for a dyno tune. The car was 'tuned' for a 100 shot and looked safe on the dyno. I think that they left a lot of stuff un-tuned and I'd like to learn how to dial it in.

Question 1
I have SVO 30# Injectors and I haven't done any calibration for them.

Question 2
I don't have a FPR installed. The car makes ~60psi at idle.

Question 3
I don't have a wideband yet. Still trying to decide on one.

Question 4
No wideband.

I have pretty open access to a dyno, just no wideband yet. What kind of WB do you have?

Thanks for the help. Hopefully I can learn how to tune my car with the info on this site.
