Has anyone messed with these injectors yet? I got some heading my way and it would be good to have a good starting point

 

ID's come with a sheet stating latencies yeah? My ID1000's did and they're available on their site too. Scaling is going to differ a bit car to car, try 70-80% of the injectors rated size and go from there using trims.

Here:

Dynamic Flow Rate and Dead Time Summary section has the latencies

Not really the forum for it but I'll answer anyway.

On gas if they are a true 1300cc I'd start with 1125 up to 1170 with the latency they provide. If its on the positive side of the trims (i.e. +15% vs -15% for negative) I would drop that number till its about -3% or so. Then drive it and you should see cruise trims somewhere around zero in steady state. Thats normally an indication its close.

MAF or SD?

 

It's on maf John

 

I just ordered the same ones.

 

I've been told they werent 1300cc on calibration fluid so these may be smaller in reality.

 

anyone have these dialed in on an 8/9? would be curious to see the values, esp for e85.

 

On my walbro 416 I was dialed to about 730.... Now with my my double pumper setup I haven't finished tuning I'm at 800 on e85 so far

 

I have had them on a Subaru on gas. They scaled like the Fuel Injector Clinic 1100.

 

800 cc/min would be about right for a 1300 cc/min injector. How is the drivability?

 

Wow. That would be way undersized for the implied flow rate because FIC1100s scale like an 1100 cc/min injector.

 

Perhaps it was the software but I started with an 1100 map on said Subaru that was dialed and had been used on a similar setup for 590whp. The car started up and was on the trims. The scaling and latency was close enough I fine tuned the rest of the idle and cruise in the MAF tables and then went to the WOT stuff later.
