For the moment run this with the flowrate dropped down to 21.1. This should richen it up a bit.

If you like, go to my links page and download Datamaster. You can use it 20 times for free. I also built a page on how to use it. Email me the datamaster file and I'll tune your fuel maps. I'm ignorant of TunerPro, and keep telling myself I need to figure it.

great guy MRWillys ,i have to work on my 85 she has the opposite issue she's very rich at all rpm range idle, mid, and highway speed 108 blms,i've lowered my fuel pressure and now she went to 114 -116,and 118 idle.FP was in the 40-41 psi (a little bit high for an 85 she runs 35-38 psi stock cuz 24lb injcs).i suspect this rich condition it's correlated to a mechanical issue (air leak cuz my idle is stumbling and IAC is continually opening and closing to compensate).

MrWillys

I do not know a lot about 85, because it is a weird UV chip, and it does not have a injector flowrate number to adjust. However, I think you can modify the Injector pulse width VS Load value table. For example.

if LV8 256 = 9384 and you want 5% less?

9384 x .95 = 8915, or your new value.

Try this and post results.

Thanks MRWILLYS i know 870 it's a bad animal.I've ordered a new spare ecm cuz i've to solder a zif socket on it to have an easy plug in of my Ostrich ribbon cable header

This table is used to adjust for injector changes. If you have 23lb injectors stock and change to 30lb injectors you would modify this table by the percentage of change 1- ((30-23)/23) = .6957, take the whole table and multiply it by .6957, and that will correct for the larger injectors.

MrWillys

Are you saying this equation works solely in the LV8 = 256 portion of this table? Would we then use a % to calculate the remainder? part divided by the whole, or 6957 / 9384 = 74.137%?

Therefore, were LV8 = 240 in the adjacent table with a value of 8774 we would then use 8774 x .74137 = 6505 for our new value in the LV8 = 240 value?

I guess I just don't understand how your equation applies to each value in the table without changing it to a %.

Sorry I'm taking so long on trying that new burn, It's finals week and I've been overwhelmed with school. Should have it burned and a report later today though.

bjankuski

.6957 is a percentage, that is what you multiply each value in the table by for each load position 9384 x .6957 = 6528 new number for 256, use this percentage of change for every load number. That is why I listed multiply this number (.6957) by the entire table.

MrWillys

Understood, thank you!

Alright just about to take the latest burn for a test. I didn't have time to read how to use datamaster so I'll be using tunerpro again. I checked my timing with a light and it shows 6 degrees but when I looked at tunerpro it showed a spark advance around 30. Whats that about?
