anewjer00 Posted August 29, 2023 Report Share Posted August 29, 2023 Hello k24 swapped 98 civic . Not many or any tuners in my area that tune with link ! does anyone have a boosted k24 tune file that I could possibly side by side . Naturally aspirated with oem injectors the car ran just fine , however now I added Comp 5858 turbo and New Bosch 2200 injectors, 340lph pump, and e85. car starts and idles pretty well but any acceleration car falls on its face. ! fuel pressure does not hold after key off, oem injectors did hold. log file and tune below any suggestions are greatly appreciated PC Datalog - 2023-08-28 10;04;34 pm.llgx fueling.pclx Quote Link to comment Share on other sites More sharing options...
koracing Posted August 30, 2023 Report Share Posted August 30, 2023 Have you verified your ethanol content in your fuel? You have no sensor and your fuel model settings are for 85% ethanol exactly - which unless you're buying it pre-mixed in a barrel or mixing it yourself, is hard to get that precise. It's running pretty rich for sure. You'll need to re-verify your injector dead times as those values seem pretty low. You're also commanding maximum VE on boost. Your AFR targets are a bit rich off boost and maybe a bit lean for on boost. Are you saying you suspect that you have an injector sticking open? Were the OEM injectors high impedance? How quickly does fuel pressure drop after key off? I would also recommend adding a fuel pressure sensor as well as an ethanol sensor.

Rossobianconero Posted August 30, 2023 Report Share Posted August 30, 2023 I'm guessing when vtec activated the engine dies... you have a fuel map for vtec on, which has not been tune or calibrate is at cero, so any time you will go to vtec it will stop injecting fuel (falls on its face). And like koracing said, your fuel map on boost at least on no vtec is max out, that doesn't make sense. At first look the timing seems conservative, should be a safe start but knock control is going to be necessary even with e85. Quote Link to comment Share on other sites More sharing options...

anewjer00 Posted August 30, 2023 Author Report Share Posted August 30, 2023 Ok , No have not checked the fuel for ethanol content and from what I have been told by everyone in my are is that it’s around 65-70 percent maximum, but I wasn’t aware I had it set for 85 percent I’ll make sure to get that corrected . Yes I was thinking I had a fuel injector sticking open due to the pressure bleeding off in less than 5 seconds . The fuel pump is the same pump I ran with the pen injectors and all the injectors I have used are high impedance . because I was so unsure about the 2200 Bosch injectors and had no tuning data for them , I now have brand new deatchwerk 1000 cc injectors and it’s running a lot better . As far as the tune file I sent over is very close to the tune I was actually driving on minus that added 2nd fuel table meaning Because I’m in process of trying to figure this out myself , I just happened to have added the 2nd fuel map because I’m trying to eventually have a high and low cam map that switches for vtec as I believe that’s the right way to do it , but had added that after I created this data log so not what’s causing it to fall on its face . The issue I was concerned about falling on its face was rather as soon as you tried to accelerate and not even close to the vtec engagement . As far as the sensors is there a fuel pressure sensor and fuel content sensor you’d suggest and are they a sensor that can be purchased at a local auto zone or auto parts store ? Rich out of boost , lean in boost and maxed out VE table , does anyone have file or picture of a closer fuel table or tables that I could start or even suggestions as to what it should look like ? I definitely appreciate the replies as that’s what I came here for is you guys rock for helping the community , you all deserve a pat on the back !! Thanks oh yeah and as for the knock table , I’m still trying to research how to set that up as well , I only have the owl sensor available as of right now and there’s a lot of info out there good and bad on setting this up so I’m eventually working in that direction , feel free to send over a file I could look at as an example of a properly set up knock control .

Rossobianconero Posted August 31, 2023 Report Share Posted August 31, 2023 the same file that you posted with knock control "setup", is NOT SETUP you will have to check what is knock at what frequency you can detect knock better with the ecu but, it will give you a idea of how would looks like. I didn't adjust the axis on the trim tables but you get the idea. If you follow the help files instructions you will be alright, for me what it work best is when I set it up for the first time is using my own knock detection system (so i can actually hear the engine), clears knock are easier to detect in both system. fueling knock.pclx Quote Link to comment Share on other sites More sharing options...
anewjer00 Posted August 31, 2023 Author Report Share Posted August 31, 2023 So As far as the fuel table goes , I have done some reading and better understand VE however Does anyone have a k24 map with a fully tuned fuel map i can look at please ! I have searched and scoured the internet and nothing out there ! THANKS VERY MUCH MY LINKMATES Quote Link to comment Share on other sites More sharing options...
