I am in the process of dialing it in. its crazy when i put it in D the idle is really good. this is it while idling in park everyone ofthose dips is spark source changing to 1
Spark fluctuating at idle my
Min is -1.25
Max 23.00
Avg. 11.00
Every time the idle drops it switches to spark source 1 and spark jumps to 22.00. So something is either causing it to
Drop and spark is making up for it or something else going on
I am chasing a up and down idle issue only in park when I put it in drive the issue goes away. Using SCT in closed loop to data log Spark Source and while idling, with the car In park it changes from 9 to 1. When this change happens is when the car idle up and down erratically. My MAF...
Thanks for the help it ended up being the Bosch O2's i switched to NTK and now STFT and LAMBDA on my gauge are in sync. Reading your fuel write up i converted to Return and kept the FRPS. Using SCT i cant find the switch to shut off injector compensation, in your write up you call it EFRS...
FYI my ECU strategy is CVAF1
So these will be the new values?
breakpoint .0000241/2.5052=.00000959
Hi slope- .00833
Lo slope- .0281000/2.5052=.0112
I didn’t see it in your write up so gonna ask to be sure. Does the Minimum pulse Width also get scaled by 2.5052
Ok I read your write up and I see in big red letters that Hi slope is single most important scalar. That being said on SCT the values are # per second. So according to your injector data hi slope for 80lb blue tip Deka is 75.157. So do I convert and use the 75.157 or like you previously...
I changed the Bosch 17025 sensor with a known good one and recalibrated it. Is my injector data wrong here
breakpoint— .0000241
Hi slope- .0208000
Lo slope- .0281000
Minimum pulse- .0005980
I am tuning my single turbo 2v with SCT PRP. when doing a in park rev log 1500,2000,2500,3000,3500,4000 rpm. I am in closed loop the STFT are within 3% and no matter what RPM the AFR is reading lean. While idling the Trims are perfect and AFR is around 17.2. If it was a air leak before the O2...
Thanks I'm not gonna adjust fuel only use the meth for added timing according to ACT. Will be running rich while spraying which is ok with me. Just cant seem to find ACT Spark adder table CVAF1 is my strategy.
I am not going to change the fuel tables once i am tuned for no meth. Gonna use the meth to add timing Only and will be rich when spraying. I do have the innovate SCG-1 with similar fail safe as the AEM. Cant seem to find ACT Spark adder table in SCT Advantage and i have calibrator status
Im installing a snow progressive meth kit on 99 built 2v with a single 7875 running pump gas twin 340lph 10an feed split to 8an and 8an return . I have PRP SCT Advantage with calibrator access. What would have to be done in the tune to only add timing according to ACT. Nozzle is located after...
