Injector dynamics
They don't modify injectors.
They are a bosch motorsports partner, and actually do design work and engineering for bosch.

And yes, I've been to their factory, down the street from my house, and watched them build injectors, the CNC machines make sub assemblies, the quality control.

Good luck with that one

The injector data ECS gave out in dudes "base tune" was just flat out wrong. There's no other way to say it.. maxing out the injector flow rate table isn't right, I don't care what injectors you're running.

interesting, so they manufacture injectors for bosch?

i still think there is no reason to bin a set of perfectly good injectors, (they never gave me any trouble and are pretty fast, actually) because of a tuning issue. i believe i have all the neccessary data for them, so it must be out there. its been over two years since i looked at this, but redhard supra comes to mind.

if you need anything specific, i can look it up, maybe.

schpenxel, you had a look at the tune? maxing out the flow rate table?

No, most injectors do not have sufficient data.

I posted the tune on this forum. Most everyone has had a look at it. Thing is there is a right way to do everything and there are obviously some that are not quite right but might work good enough for some people. Every combination is different. I have exhausted most every avenue to correct the surging problem. Some very experienced tuners have looked at my tune and we have tried to make it work even with the wrong data. Some people might be satisfied with the way it runs now as the surge is not that bad but I am not the kind of guy that accepts good enough. I want it right and I will spend what it takes to get it right. I not only ordered ID 1050 injectors but ordered a DSX upgrade ECM with a base tune in it and the right injector data preinstalled. Some might say it's overkill but to me it's the cost of having play toys and going fast.

so i read your other two threads (i even posted in the second one complaining i coudnt open hp files anymore, i still cant) and had to smile, because everybody was saying the same: can be tuned out. unfortunately well never know what the issue was, as chances are good that with another ecu and os the problem will go away. good luck with it.

And yes that is why I ordered the new injectors and ECM... So the problem would go away.

I installed the injectors with my original ECM. I scaled them using the double stoic/half IFR method. Surge is gone! I had to work on my fuel trims some but car runs way better. I also ordered a DSX ecm but had to send it back to have the fuel gauge data installed and some adjustments done with the idle. It was my fault, I should have sent them my tune from my original ECM and i wouldnt have had to send it back. DSX was quick to get it back to me even with the hurricane! I have installed the new ecm but have not had a lot of time to work on the tune. The new ecm uses the ve tables and i am having a hell of a time getting my fuel trims sorted out. Seems like it was easier with the vve table on the old ecm but I'm sure it's just my lack of experience that's the problem. I will say I am a believer in the injector dynamics injectors!

so what is the offset of the new injectors and are they flow and offset matched?

i have a new computer and can open your tune now, but where is all the injector stuff? i only see flowrate.

yes, that did it, but i see some pretty weird stuff in there. but thats probably because i dont know what im looking at. mpw 0.125? volt/map zeroed out? virtually no pulse adder? what was it again, a 2005? still the original ecu, right?

07 and this is DSX ECM. Injector data pre-installed. The injector date is available on Injector Dynamics website.

All of that is fine. Offset vs. pressure vs. ign voltage and short pulse adder are where all the adders are. Min PW is fine that low

Ok, the original ecm is back in. The car just didn't act right with the new ecm. At slower speeds when giving it the throttle it acted like it was pushing a dump truck. If you gave it quite a bit of throttle it acted dead just didn't want to rev up quickly. I tried changing the timing tables and worked on the ve tables and nothing made any difference. Not sure what's going on and I know I'm no tuning expert but when I put the original ecm back in it runs fine. I actually had the car running pretty good before I changed the ecm but I thought the added tuning features would make tuning more accurate and easier to do.
