I have 445cc from injector clinic. They are data matched and come with the details you need for your ecu.

ProTunerz l-series intake manifold w/ throttle body + fuel rail
DuffyMahoney replied to softopz's topic in Vendor's Forum
I can't wait to see flow data! I bet it will do well. I would buy it just for the looks. So much better then the stock. -
Well my injectors are fine! Gosh I hope it was the spark plugs.

Tioga has been helping me a lot! I think I have a better handle on the haltech software, which is very complicated. A few things we have found/ learned I was using stock plugs, which I switched in at some point. I upgraded to plugs with resistors (BPR6ES) I was attempting to use throttle % for maps, but no map existed. All were map. So I don't know what the ecu was even doing or deciding what do to. Tioga gave me some helpful maps to use as a base for throttle % based tune. I figured out how to turn data logging on. I am kind of hopeful that the spark plug without resistors could be my issue. Causing feedback all across my ecu and wiring, and causing the injectors to drop or misfire. Gosh that would be a easy fix and dumb of me to miss that. Thanks again Tioga!

Project hand throttle is done and working. Should help with cold starts with my ITB. Until I get my iac system sorted out. IMG_6219.MOV

My elite 750 has 6 drivers. Wired directly. Spark plugs are definitely fouled.
-
Tach follows what the software is saying for rpms. Spark seems fine, but also on my potential list. But I don't believe that would cause the injector strange clicks. Lets wait to see what injector labs says. Then move on from there. I am hopeful, it sure would be an easy fix.
-
I have data logging turned on. But it’s not saving. I will ask haltech what needs to be done to fix that. Originally the tuner only had it turned on after a certain rpm. I just found and fixed that setting. I’m getting fairly good at the haltech software. But it’s a pretty steep learning curve. I have dual Haltech o2 sensors, plus fouled plugs plus terrible odor. Currently it won’t get above 11. That’s even running the injectors at like 10 out of 100 in the software.
-
The issue is what is causing the the injectors to miss fire out of sync with the motor, and so loudly. You can hear the normal/ feel the normal clicks of them firing correctly, then it will be just odd giant clicks randomly, the motor stumbles in these moments. I believe it's just a dumping fuel at that moment. Is it the ecu, setting, trigger or a fault in the injectors? Since it ran fine prior, which is when was running 1-3ohm in the settings. Then got worse, I am guessing it's something that slowly broke. Like a winding on an injector. Or the ecu.
-
The map sensor on my haltech is built in, which is the one that I am using, it's part of the ecu. It was reading correctly, I just don't remember what psi it was pulling at idle. Settings are correct. I am thinking trigger errors will be one of the next things I troubleshoot.
-
Sadly I tried turning off o2 correction. Coolant temp and such are spot on. I use psi and didn’t write it down. But it’s pulling a strong vacuum. Especially my balance bar intake.
-
It will idle below 1300. The terrible clicks go away above. It runs crazy rich no matter what though.
-
Thanks guys. I don’t believe it’s a setting. But I could be wrong. It slowly got worse and worse which has me stumped. I trust injector labs and the owner. He has been great. He also claims he doesn’t think it is the injectors. I made the decision to test them when they stop reacting to commands. Basically steps towards finding the issue and resolving it. My guess is they come back fine and then next I send the ecu in. I tried early tunes that had everything correct and used to run fine. Basically the first tunes, before we started the process of tuning via the fuel maps. I was told that the wiring thickness would be different inside the coil on the injectors. Lower ohm would have more robust windings. Higher Ohm would be thinner, higher ohm coils are actually smaller diameter as well. Again, I’m not an expert or electrical engineer.

I own a brewery. We have solenoid valves on most of our brewery tanks. Sometimes when they are dying they make these crazy random clicks. I believe it’s the coils shorting. The injectors remind me of that noise. Time will tell. The car did run awesome, just for reference.
-
Yeah all possible culprits. I will start that after I get the injectors back. I guess it’s a few days turn around.
-
Not pissed at all. You are guys are super smart. I’m a huge newbie with all of this. One thing I forgot to mention. The injectors have slowly stopped listening to commands from the ecu. So strange. I literally can’t get the afr to go above 11. No matter what I do.
-
You guys are all way too smart! All way over my head. The engine starts and runs terrible, kind of like a terrible tuned carb that’s super cold. I’m hopeful it’s injectors but both haltech and injectors labs say I could have caused damage. Haltech believes the ecu should be fine but has never tested running the engine a lot with the wrong ohm setting:) Injector labs said they could hear the click in the video. The clicks don’t go in time with anything. They sound almost completely random. Also go away as soon as I’m above 1300 or so rpms. I have gotten a few trigger errors. I will try to why what they were. I need to figure out my data log. So far that doesn’t work.
-
Well it's either the ecu or the injectors that have an issue. I am sending the injectors off to be tested by Injector Clinic. That is where I got them. Fingers crossed, that would be the cheapest fix!
-
I understood that lower ohm was opposite. So 1-3 would require beefier internal wiring. So running a 12ohm injector with 1-3 ohms with thin internal wiring would Ruin them? I'm not an engineer at all. I should have asked more questions. I don’t believe the haltech has anyway to test without the car running. I know some ecus do.
-
I asked an electrical engineer buddy, he doesn't know much about injectors but said low ohms towards them could have fried the windings? Super common in the car speaker world, which I am more familiar with. You can't send say 2ohm to a 4 or 8ohm speaker very long till it ruins it. Very common for people to wire speakers incorrectly and damage the speaker or the amp. I guess I could have damaged the ecu? I asked injectorlabs about it. Waiting to hear back. The video doesn't show the sound that well.
-
Well, I at some point I must of changed the settings in the haltech software from high own to low ohm (should have been set high or 12.8ohm) , then over the next 15 hours of tuning I believe I have ruined my injectors:( The odd clicks are coming from the injectors.
-
I should have a test bracket in my hands soon, maybe tomorrow?
-
I had a throttle body not seated all the way. I switched from studs on the intake to bolts and it fixed it. I am in the middle of tuning and trying some settings. Frustrating, but also sort of fun! There are so so many settings! I am also trying to track down a weird hesitation that seems to come and go, so either spark or fuel. I kind of wish I would have made a hand throttle using my stock choke lever for bumping the rpms for warm up, sure would have been easier. With the same tune, the engine doesn't run the same with the large balance bar. Also have the balance bar after the injectors isn't ideal.

All will be checked, but they should be spot on for the $.

It’s on here somewhere
