Randall Posted February 22, 2013 Author Share Posted February 22, 2013 (edited) I feel like an idiot... I was so frustrated last night and almost burned up my starter in the process. So I gave it a rest. This morning i cleaned up the distributor again and reset all of the air gaps. Set the motor to tdc, set plug wires back to stock. put in 0 degree offset in ms turned the key and it started right up and ran smooth. Then i just turned the distributor slightly to get the correct advance as my fixed timing was set to in megasquirt. Here is a video: Only problem left is i am getting different readings for my AFR in Megasquirt when compared to the LC-1 Gauge. All grounds are at the same place for both megasquirt, LC-1, and gauges. Edited February 22, 2013 by Randall Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted February 22, 2013 Share Posted February 22, 2013 I would use the Lc-1 readings even though I personally dislike them. Glad to hear it run. Quote Link to comment Share on other sites More sharing options...
Randall Posted February 22, 2013 Author Share Posted February 22, 2013 What do you mean by LC-1 readings? The gauge? Because LC-1 goes to both the MS and Innovative Gauge. The gauge seems more accurate because when it is idling at its best the gauge shows around 13-14 and MS is showing like 10 or something ridiculously rich.

NewZed Posted February 22, 2013 Share Posted February 22, 2013 I'm not positive but I don't think that you can run two devices from one O2 sensor. Might be part of your problem. Quote Link to comment Share on other sites More sharing options...
OhBilly Posted February 22, 2013 Share Posted February 22, 2013 You probably have your wideband configuration set wrong in MS. You'll need to open up the configurator and dive into the settings.ini file to set it correctly. At least that's how it's done in Megatune, not so sure about TunerStudio.

loy Posted February 22, 2013 Share Posted February 22, 2013 Lag factor I believe plays a role. In tuner studio to set the wideband go to tools then calibrate afr then choose your wideband. Quote Link to comment Share on other sites More sharing options...
kaito Posted February 23, 2013 Share Posted February 23, 2013 Yeah that is what I meant. Timing was fixed to 0 in the table and trigger offset was set to 60 then I turned the distributor until I saw 0 while cranking. It was late last night so I have not verified timing while it was idling Thats how you do it. Like the other guy said though, make sure you check it agin for accurate timing and make sure when you are running it with an actual ignition table that it reads what it says its supposed to be.

kaito Posted February 23, 2013 Share Posted February 23, 2013 Oh and btw LC-1 sucks. Try zietronix, I have the zt3 and love it. Quote Link to comment Share on other sites More sharing options...
Randall Posted February 23, 2013 Author Share Posted February 23, 2013 Yeah I've done everything calibrated ms for LC-1 all grounds for ms and lc1 go directly to the battery. LC-1 has 2 outputs one for their gauge and one for ms. I think the controller is possibly messed up cause I've gone through the wiring with a multimeter to check all connections.

Randall Posted February 23, 2013 Author Share Posted February 23, 2013 Well figured it out the LC-1 comes with 2 analog outs that are both pre loaded one is a narrowband voltage and the other is a wideband. So the gauge was seeing the wideband voltage and MS was seeing the narrowband but expecting wideband voltages. These outputs are programmable so i just set them both to wideband and everything is now good. Now onto the cars first datalog while driving. Still breaking it in so i did not go over 3000 rpm just kept varying the load around the neighborhood. I kept getting some random lean spikes using cygnus' maps with the advance locked at 20 (still not sure the timing setup is perfect so i just locked it at 20 for the first drive). Let me know what you think. 2013-02-23_01.23.19.rar Quote Link to comment Share on other sites More sharing options...
Randall Posted February 23, 2013 Author Share Posted February 23, 2013 BTW if i set my timing and use a fixed advance when i rev the car it jumps up another 10 to 15 degrees Quote Link to comment Share on other sites More sharing options...
Randall Posted February 23, 2013 Author Share Posted February 23, 2013 Got the timing stabilized by switching the input capture and it only runs with an offset between 0-10 offset. 45 works too but anything higher wont start. Now I'm getting random lean spikes all over the place with no rhyme or reason. I believe they are misfires dont know why it is cutting out Quote Link to comment Share on other sites More sharing options...
skirkland1980 Posted February 24, 2013 Share Posted February 24, 2013 Yeah it's probably misfires. How do the spark plugs look now? Quote Link to comment Share on other sites More sharing options...
Randall Posted February 24, 2013 Author Share Posted February 24, 2013 They are brand new bpr7es I believe whatever everyone recommends on here. I left them gapped at .35 which is what they came with. They look fine just a little rich. Motor seems to be breaking in fine with 19 to 20 inch of vacuum at idle and 23-24 on decell Right now I have the VR line to mega squirt ran the way the original lines were which means it runs next to the coil and next to the alternator Would it be better to run it up along with the injector lines or will the injectors be even noisier?

skirkland1980 Posted February 24, 2013 Share Posted February 24, 2013 Your last data log has no data. Can you upload your new newest msq and datalog? Quote Link to comment Share on other sites More sharing options...
Randall Posted February 25, 2013 Author Share Posted February 25, 2013 (edited) Here are some datalogs... First one get into third gear and floor it and let off when it it hits lean. Then i do the same in fourth. Next map is the same except i increased req_fuel just to see if it was a misfire or running lean. I can see in the second datalog that the req_fuel did help my afr's Also i have my wastegate tied open so the car is not seeing boost.

skirkland1980 Posted February 25, 2013 Share Posted February 25, 2013 There is still a problem with your datalog files. They need to be in a compressed zip folder. Quote Link to comment Share on other sites More sharing options...
loy Posted February 25, 2013 Share Posted February 25, 2013 They open fine for me. Quote Link to comment Share on other sites More sharing options...
Randall Posted February 25, 2013 Author Share Posted February 25, 2013 (edited) Here they are in a .zip format... I think the problem is the stock FPR im seeing about 20 psi at idle and when i blip the throttle sometimes it will actually drop. Going to get some hose so i can relocate my Fuel pressure gauge so that i can see it while driving. The pump is a new Walbro 255 with a 40 micron pre filter and 10 micron post. So its not dirt and i dont believe to be a bad pump although this pump does have a pretty loud wine to it. I tried adding fuel where it leans out with almost no improvement so that only leads me to believe that im not seeing good fuel pressure.

skirkland1980 Posted February 25, 2013 Share Posted February 25, 2013 Ok cool I got it that time. I think you're on the right track. It does appear to be leaning out at WOT. Can I also see your newest msq (tune) also in zip format? Quote Link to comment Share on other sites More sharing options...
