ID2000 scaling and latency

The only reason I ask is because from your 1050s statement, it sounds like you were getting proper fueling, but on pump gas, that would be too much fueling. The IPW cranking/starting, running, etc all need to be tweaked to properly start cold/warm/hot.
Of course, since your friend's car starts fine and you used his ROM and still had the issue does lend itself to being a hardware issue. Curious as to what you find with the ECU swap.

Are you tuning the various IPW and/or ISCV tables that have been found?

I am curious as well......and I will post up the results in a few weeks when we hopefully get to make the swap.

I think it has to do with how the ecu does an IPW during startup then at some point switches over to the MAF to fuel the car. I think travis's car just doesen't crank at the same RPM or just doesen't make the switch as cleanly as mine.
You know, it could even be that I have a stronger spark system when cranking than he does. Maybe I have a better battery, maybe I have more voltage, maybe I just got a good set of coils and one or two of his are slightly weaker.
We have went so far as to run our tanks low and fill up at the exact same fuel pump at the exact same time.
I have a spare ECU that I am going to put into my car to see if it follows the ecu. Perhaps some ECU's have better drivers than others, we shall see.
The issue I feel is hardware not related to the injectors. It has something to do with the evo. The problem is with every brand of injector. This is not one reason to pick any other injector over the Injector Dynamics injector. If you want the best get the ID injectors. If you want something cheap, buy something else.

I was really tempted to move toward the ID2000 after seeing the video of that integra. Unfortunately I had been short on time and hadn't seen the price. Almost a grand is a little too rich for my blood, but I will say they are worth it (based on data and trusted reviews of it's accuracy) if you have the requirement.
I've recently played with my latencies for my RC1200 again and they are driving much better on E85. We'll see if it continues with pump and if I can make a decision weather or not to go red and stick with them or down-size to the ID1000 next year if pump doesn't run through them well.
This image really says it all (linked because it is large)

I don't see what the big deal is. The 1600's are kinda linear down to about 2ms. Who uses and injector at 2ms anyways? I mean sure my idle pulsewidth on 1000's is 2ms so on 1600's it would 1.4ms or so but what is the big deal? I'll just run 10:1 afr at idle to get it to all work. /sarcasm

I would like to clarify and earlier statement and make sure that you all know the post was edited as well. I refered to some injectors as firehoses this was not the BlueMax series which I use in customer cars very often since we are a Master Distributor. I had been talking about the older Ford 150 and 160# (1600 and 1680) designs that were new technology back in 1985, not the current releases from FIC.
I am going to be trying some other injectors/parts in the near future on my car (both on gas and E85 and most likely pre 2.2) to illustrate some of the other options as well. I will do the same thing I did in this thread and have all the relevant maps, fuel type, current combination, and injector information listed.
Thanks for reading,
Aaron
