Setting idle

Re: Setting idle
My comments are in reference to the A9* family
The stock A9S values yield a ICS daspot prepostion value of closer to .26,(not .2), at 672 RPM. I am still unclear if the units are Lbs/min or ISC duty cycle. If in Lbs/min, this means the EEC has to add .26 Lbs/min more than TB air flow to achieve 672 RPM over the base 550 RPM. If the units are ISC duty cycle , then the fuction becomes easier to understand and use. I can't find "ISC transfer" function within the A9S parameters.

Re: Setting idle
According to the ISC transfer definition in the GUFB strategy book the Y axis is ISC Duty Cycle and the X axis is air. I am also assuming that the units is in lbs/min.
TT331FB glad to see you here

After looking into the A9S binary, the ISC transfer function is identical to the A9L. It is in the same memory loaction as the A9L.

ISC Dashpot Prepostion has Y axis air and X axis RPM. We talking the same function here? PS Missed you at the Reno Restomods show!

Re: Setting idle
This is for the ISC transfer function:
Air = 0x7256 scale / 4096 Duty Cycle = 0x7258 scale /32768 This is for the ISC Dashpot Preposition: RPM= 0x7346 scale / 4 Dashpot Clip = 0x7348 scale /4096 They are different functions. Eric my name is Clint not Mike. I wish I saw Mike there too. I was there at the restomods with you. I had my father there with his blue 66 and red 65. Hopefully you can remember.

Re: Setting idle
Sorry Clint, Sure I remember you guys and the cold dricks you shared!
The ISC Transfer Function appears to be an A9L function, not a A9S function. The A9S only has ISC Dashpot Prepostion. I thought the two processors were the same, I guess not! Thanks, Eric

Re: Setting idle
The processors are very similar, but a few of the memory locations are different. I just looked at both. I have about 30-40 more parameters and about 3-4 tables and a bunch more functions.
This is due to me doing binary searches.
