Pretty new to HP tuners, and efi tunning in general. I have a gen 3 lq4 with 60lb siemens injectors, 78mm on3 turbo with 8psi spring. Its running on e85 and i noticed my tune doesnt need any of the flex fuel OS's. I was wondering how the tune differs to a similar tune but on pump gas.
How do you tune spark tables for ~14psi boost if the table maxes out at 1.20 cyl airmass (g).
PS something cool I did today was feed my innovate wideband analog output to EGR sensor positive wire. Now in HP tuners I can see wideband voltage in EGR sensor voltage data, and use this with a math function to calculate AFR. No need for prolink now
