I need a set of injectors as well, but where to go so the right size and data sheet supplied? These are for a TPI set up on a 383..
for 'reasonably cheap' but good, i'd look at racetronix's injectors (accel's newer black/silver metal body are **the same injectors**). they seem to have a good spray pattern, good data sheets, and aren't crazy expensive. my last set served me very well.
ironically for a 383 tpi, buy the LT1 injectors from this guy when he takes them off, since that tpi's VE will fall off on the top end, they'll probably be plenty of fuel.
how do u Change To Fuel/Air Ratio Vs. RPM at WOT? whats each part of spread sheet mean?
are you using EE with my xdf file? or is this a '92-93?
from the tunercat help file:
WOT % Change To Fuel/Air Ratio Vs. Coolant Temp.
This table is the percent change to Fuel/Air Ratio used at or near wide-open throttle (WOT) versus coolant temperature. The values from this table and the WOT % Change To Fuel/Air Ratio Vs. RPM are summed to arrive at the WOT Air Fuel ratio.
The resulting air / fuel ratio can be calculated as follows:
WOT AFR = 14.7 / (1 + %Change vs Cool/100 + %Change vs RPM/100)
For the selected RPM, suppose the percent change to Fuel/Air Ratio from the RPM table is = - 5.1 and the percent change to Fuel/Air Ratio from the COOLANT table at the selected coolant temperature is = 22.7, then the approximate WOT AFR would be:
14.7 / (1 -0.051+.227) = 12.5:1 AFR
(in other words, higher numbers are more fuel, lower numbers are less fuel..... and a total of 13-14% in rpm and coolant temp tables should be close to a good AFR)
I got my injectors from these guys. Great prices and these people know what their doing.
