    Default RTACS Progress

    Finally got a break in the weather and life schedule to play with RTACS again today. Anybody else care to share their experiences with RTACS? I am having a ball with the VE table. Specifically, can anybody elaborate their experiences on/with applying RTACS to the Idle>Throttle Cracker, Follower tables?

    I am kinda bummed by how little (public) feedback is/has been published so far. I have been hoping that like at a really good dinner there is little conversation as the participants are so indulged in the really good meal they have little time without a mouthful of food.

    brmmmr bbkjd hmmmm <finishes big bite> yeah, RTACS kicks ass. I really went nuts with my VE tables, started working on some idle stuff, and have had the bird parked for the better part of a week now.

    Setup something for idle but couldn't get it to update the table properly. Also not sure of the relationship between the table and the desired airflow PID. Logged values differ from those in the table.

    Will wait and see what the update does for us.

    Ah,...ehm... squeezing legs together.


    After finally putting the demonic LC-1 issue to bed today finally once and for all I am back on track. (Had to RMA the controller, (RTACS worked great)(Then went insane) then exchanged the sensor) and finally RTACS = razor sharp VE table. Ready to jump in and help others with the VE table, RR, RTACS; but still haven't had enough system up time to experiment enough to get the 2D tables to work. I'd really like to get this nailed before my trip to Madrid next month.



    How's everybody else doing?

    Did some dyno tuning on a 2000 LS1 camaro today using RATCS. It worked like a charm. We did the full nine yards on this car. Upgraded from a 99 OS to a 02 first. Then upgraded to COS 5 from the 02 tune and finally after many hours of upgrading got to get on the dyno for some fun stuff.

    This car has a 600+ lift cam and patriot stage II heads. It crawed onto the dyno running very poorly. Took about 30 min to get RATCS configured correctly to work with the LM1 setup and after doing so, took about 2 min to get 90% of the VE table dialed in.

    It was very confusing at first to get the RATCS setup to work and to figure out how to set up the filters, but once we did, PRESTO. Finished the Dyno tune in 4 Pulls with ease. I would highly suggest this to anyone that wants to tune there car correctly as it will walk you right thru the VE table. Glad to hear your doing well with it also.

    That's really cool thanks for sharing your experience. Best thing since sliced bread eh? When you break it down really this system is a revised fuel trim system incorporating a wideband O2. HPwhat
