Frost - might need to set a date with you to just start over from scratch on this :(

:hi:

Thats exactly what I wanted to hear. This is my first cam'd car (the rest were all stock + boost applications) so I'm new to what a cam car drives like.

Welcome to the world of overlap I guess! ...

Thanks Bill.


I've gotten to where the car is very drivable but I still get a little bucking from in the lower RPM range under light throttle.

I thought I read that a few people changed the...

Sorry Bill, I misread that. Table 10 in the Histo.

IDLE AIRFLOW, VE AIRFLOW

Trying to determine how these numbers apply to my base idle airflow table.

just wanted to update this thread a bit -

Here is the lasted tune along with a short scan I performed tonight.

I'm still chasing down some surging in the 1500-1000 range- mainly in gears 4-5...

This is very interesting. I just got an email of the original tune when this car was running a MAF (attached).

It looks like someone pulled the MAF, failed it, then just inflated EVERY table....

I'm loving this car more and more as the idle improves. OK I redid the scan and make some minor adjustments to the airflow. Idle has DRAMATICALLY improved. I used the average idle air numbers from...

Got a response back from the actual builder of the engine:

thats the plan for now. you got me that far :)

By QM600 you mean cam - nope. I'll list the specs as this should help. Maybe your tune would have some good starting points for me. I'd appreciate you emailing it to me:

The numbers I got on the RAF were 3.6 across the board. That doesn't seem right at all.

Tried it this weekend and failed. For some reason it got worse. I got my adpative idle down to within +/-1.5

This car is possesed so I've put it up for sale:

Just so I understand this correctly:


We determine the TRUE air flow min by ZERO out the table then taking whatever number comes up in histogram 10 and paste it in as now a Airflow Min number...

Got to run it around town today. Now I'm getting a big drop in RPM when I engage the clutch at higher speeds/coasting.

Attached is the latest and greatest log along with the tune. The change from...

After making the changes a few things happened -

The car started up within 2 seconds without having to touch the throttle - :worship: to you Bill

Secondly, given that it started so well I...

Per your instructions here is a scan file with your recommended config.

any word on this?

Here is my current VCM pull.

Just sent my note to customer service to get my application stuff figured out. Sitting here with the editor tool up dying to add some credit and get to scanning started.

I've read a few books on tuning and Friday I'll be picking up my very own copy of HP Tuner Pro!

Making great progress. Just got a copy of the previous MAF tune before someone pulled the MAF and...
