Hell yeah, car is so much better now. Those PWs were pretty damn close to perfect. Car is smooth and doesn't buck or surge like it did before at low RPM stuff
Can I quote you on that?Originally Posted by BlackSS/SC

I'll get on the 'woot-wagon' for Steve as I just tried it on a 427 last weekend and in OL-MAF and no WB I got them to behave very well, car idles at about 2.1ms warm and 2.4-2.5ms cold.
Wow! Thanks Marcin. I'll take that compliment!Originally Posted by redhardsupra

The 79# Racetronix do the same thing but worse.
Nobody has any info on the set up anywhere. Tried using the 60# specs and it still miss fires at idle/off idle and has no power. I was better off with 102% DC on the last injectors.
I feel as though I own the only set of 79# injectors in the North American continent; or at least know ones talking

Good work guys
I may be able to give some perspective.
I'm running Siemens Deka 62s on my NA 358 96 Impala with a retun fuel system.
This may give some validation to the numbers as it is a basic hyd. roller build with a simpler PCM OS.
No IFR on this ride just a simple injector constant.
No flow rate modifier... the injector constant goes up to 2500lbs per hour.
SPA table logic is different min inj pulse and Low Pulse width offset...
The motor is ultra efficent and under sized for the 62s.
Two stage dry kit and 700RPM will take care of that in a hurry.
The point is I'm seeing .7-1.7ms at cruise on the freeway.
I can actually see .7ms under load at 14.7 AFR.
I can do steady state driving on the Low pulse width offset table.
*that is if my scanner is not lieing to me.
If I can get accurate injector offst vs system DC I can actually test the low Pulse Width Offest table under load VS the WB.
I can check it in MAF or SD modes as I had a SD and MAF tune that worked great with 42s.
I am running a blanket 977 usec injector offset vs battery at all normal system voltage ranges for now.
Anyone want to take a stab at what my Inj Offset Table shoulb be on a return fuel system with a intake manifold vacuum referenced pressure reg.
For now I will try
I have ended up with a Very steep low pulse witdh injector offest as well.15.99 0.33886
15 0.33886
14 0.41210

I'm not quite done with this table seems a that it may not be steep enough at the bottom as it goes 16.5 - 17:1 just a hair before DFCO under .8ms.
And I have a rich spot at light cuise that is very narrow in kpa, my guess is .976-1.100ms.
Hope this helps

I have done bigger badder LT1's and 433 and up cube LS1s with SD62.
But they are thirsty and dont quite sip fuel like my little 358 LT1.

How come the table posted here is different from the injectors PDF?

This is what i'm using ( I have tried more than 100 combinations since this).
It's always the same result...
Settles into a 13.5AFR idle
Misfire in cylinders #2 and #7
Hesitation off idle with no power
Goes real rich if you give it any pedal
