Will someone please send me a datalog?
 

I am having some weird issues with my FRS on startup.

Would someone be willing to use their cable and ecutek software to record me about the first 1 or two minutes after startup? Please start saving the log file before you start the car.

Either my fuel system has air in it after my new port injectors were installed or I'm worried I screwed something up :( I have logs of my car when it was stock, but I never thought to actually log the startup....

Thanks in advance,

Aaron

here

change file type to csv

did you reflash to account for the new injectors?

btw what problem u have cuz i have problems too after my 1000cc installation

I haven't worked on a return less fuel system before and I am wondering if I have a bunch of air in the lines.

Also we kinda skipped a step yesterday and wanted to start the car before bolting all the brackets/covers back over the injectors to check for leaks. Bad idea. The stock ECU grounds through that bracket.

Aaron

did you reflash to account for the larger injectors? I'm sure a 6ms pulse width on the stock injector will put out quite a different amount of fuel than a 6ms pulse width on a DW700 or DW1000.

wait are u talking about the EDU
injector module??

Yes

so the 3 bolts holding the EDU has to be there or it will cause a ground problem?

pretty sure all 3 don't have to be there, as my bottom one is missing.

lol
i dropped mine

Yeah, I don't think it specifically needs to be three of them, but it needs to be bolted in place if not the car will not start.

Thanks guys. Here is a screenshot of what I am looking at. I think I screwed up my injector scaling and just need to seriously reduce the amount of fuel spraying in there. At first I thought I was too lean, but now I am thinking I am too rich. It is next to impossible to use a wideband at this point in tuning btw..it's either not enough exhaust to really show up, or incomplete combustion because of a cold motor, or cold sensor, etc..so it's basically change and test, change and test..not a problem with a stand alone, but kind of a pain int he ass when reflashes take several minutes.

Oh my log is on bottom, WhiteFRS is on top.

Looks like his hunts like crazy when it first starts..but his starts way faster than mine. Mine basically cranks and cranks until the port injector drops to 2 millisecs, then it sorta stumbles to life. I think I am drowning the poor thing.

Aaron

The ECU/CPU to the bracket over the passenger side port injectors. Is that the EDU? Or is the EDU the other electrical box that (I think) drives the direct inejctors?

Aaron

Also whitefrs, what size injectors are you using at the time of this log?

Aaron

You guys are funny. It would probably work fine with just one. We added a short jumper wire with alligator clips to test our solution first.

Aaron

1000cc but i forgot to mention im on e85 which has 30% more tfuel than 93

Me too. Thanks 1000 times. I won't get to upload a new tune until Monday but you have given me hope!

Aaron

@mad_sb is who i would bug.

Here is a video of my issue

Who tuned yours? If you get a chance over the weekend I'd like to see a log of that problem.

Are you using the speed density racerom feature? Or still using the air flow meter?

Is the issue new? Or has it been there since the tune?

Aaron

Your tuner needs to figure out the proper injector scaling for the injectors and E85. E85 is a bitch on cold starts.

The one on the passenger side with the bottom bolt almost impossible to reach.

I had it
Then i dropped it lol

I did the same thing a few days ago. Left the injector ecu hanging there so I could check my new port injectors for leaks. 4 fouled plugs from a flooded engine/stalling later I was able to get it dyno tuned today. Always make sure that thing is grounded. FYI it started and idled fine after I grounded it. It misfired in boost over 6psi though. New oem plugs and we had no issues up to 10.5 psi. Lesson learned

Me too. Luckily my buddies (@EN2_Squirrel) had grabbed a magnetic telescoping tool when they went out for coolant for me during my Innovate SC install.

So u saying that not grounding these will damage ur plugs?

Maybe thats whats wrong with my car

My car acts like this when there is a vac leak
You sure you not leaking air somewhere?

No idea really. My car was super rich at startup, stumbled like crazy, then stalled itself out. I tried 3 or 4 times. Then when we realized that the injector ecu needed to be grounded it started and idled fine. Once on the dyno it misfired in boost, which it never did prior before this mishap

but WAS misfiring at cruising but not anymore. but i have a really hard start and they say that it can be a ground problem

Didn't see this post till today. I can shoot you some more startup logs if you need them. My car cold starts and warm starts perfectly everytime.

I know what your car's problem is. No Full Blown powered car will want to start with that music playing in the background. I didn't realize you are running full speed density either. My understanding was that EcuTek hadn't perfected the speed density modifications yet.

:lol:

Since Miley Cyrus was twerking that song car will act weird lmao

Looks too me like you have way too much cranking enrichment, you can see where it needs to be based on what the injection time is when the cranking rpms start to ramp up just as the engine fires off. Stock ECU goes into flood protection mode and starts dialing back the cranking pulse width if it does not fire right away. If it is a long crank then fires you have too much enrichment, if it take multiple cranks before it fires you don't have enough.

How about mine lol
