Compression is solid. Recently tested. Attempted tuning was done at Trackforged performance. Long story short, I got the car running with Claudios help. They did nothing but assume I installed something wrong.

I'm going to mess around with it more tonight and report back

 

So, are you pumping the throttle when youre trying to start it?

Also do you have that ignition advance purposely set to 50 degrees advanced?

Also your map is reading -2 psi when the car is completely off which isnt good.


Can you

stop pumping the throttle

Verify which MAP sensor you are using

Modify the timing advance map?

 

Yes I was pumping the throttle. Using the gm 1 bar sensor.
I'm not sure why it's defaulting to 50 degrees in the datalog. I could mess with the map but I'm not sure what to adjust or by how much

 

It sounds like you need to get over the fact that you don't want your tuner to know you were dicking with stuff and let him do his job You pay him for a reason. Stab the CAS correctly and let him work with that.

 

Well i think your map sensor isnt accurate. is it possible to use the onboard Map sensor?

I already said to do that, but im just a dumbass.

 

It was reading 0 previously. I will check the sensor tonight. It's a brand new sensor. This is an earlier model e6x that doesn't have the internal map sensor.

Unfortunately, this was haltech support who has been helping me. I may just call them on Thursday and hopefully get the car running again.

 

if you read the thread regarding the "tuning", i would wager that part of this issue was in fact their fault.

reading through everything wrote and how he had to help even get his own car running again by providing information/basemap settings to the genuis who was tuning his car all i could do is facepaw.

if the lead timing is in fact 50* advanced during crank, well that's probably the majority of it if not the whole reason why it won't start. check the idle and 500/1000rpm timing maps.


what i would suggest doing is just save this craptastic map and load up a basemap from something else, anything else 13B powered.

 

I'm sorry if I mispoke. this map was supplied by haltech and remote tuned by them after the local tuner couldn't or wouldn't do anything. . Claudio from Haltech is the reason the car was running. When it comes to tuning this thing, I'm in way over my head in terms of my abilities.

I will check the maps tonight and post screen shots of what the ignition settings are at during those ranges. What is the lead timing supposed to be when cranking?

 

0(which translates to -5*ATDC)

you could technically run it up to 15*BTDC during crank, but any more than that and you run the risk of kickback misfiring.

 

^LOL. WHY THE HELL IS MINE SET AT 50 THEN?!!?!?! Wow, ok. Sorry for yelling, I will check these maps within the next hour and a half when I get home. I did post my regular ignition 1 map on page 1. I should mention that I have the timing lock set to "on" right now.

 

i don't have halwin installed on my home computer, so i haven't checked any maps or logs.

 

The screenshot up there was the gist of it....

Cause youre a weenie.

 

lol. Truth does hurt. So after reviewing all my maps, nothing indicates the advance is set to 50. I'm not sure why that is the only reading I'm getting.

 

post ur map

 

I got it to fire FINALLY. Maps are posted. So are some datalogs. Reset the cas per factory and set trigger angle to 65 and tooth offset to 11



It fired a couple times, idled for 2 seconds and then died.




I'm not sure why the ecu isn't reading the cas signal at all. The value in the datalog says null next to it. I've verified the wiring over and over again and it ran before. Did I kill something? The ecu is reading RPM when cranking.

 

post the actual map file

and i can tell you this. It looks like youre not running a coolant temp sensor. if thats true, disable coolant correction. Also your fuel maps look super rich. from the datalog, your injector times are hanging around 7ms. should be like 2ms.

I think i had my data log settings wrong last time, cause now its at 5 degrees ATDC.

 

Check the wiring where it physically enters the CAS case. I've had the insulation crack due to age and the wires intermittently short together causing a no-start situation.

 

A man seriously, you should just restab the CAS and start with a base map.

 

i seriously hate troubleshooting when things aren't set correctly, you have multiple issues. 1 is the unknowns with the maps, the second is the improperly stabbed CAS.


i don't know about the ECT, as voltage is at 0v, somehow logging with the ECU off? shrugs, assuming it is just in offline mode.

 

I did re stab the cas to the proper setting and I am running a coolant temp sensor. I think something is wacky with the datalog as the haltech is reading the temperature when on. Wiring into the cas is fine. The car is now consistently turning over and sometimes idling for 5 seconds before it dies. I'm assuming this is due to my stupid high injector times when cranking.

I really need to lean out the injectors a bit upon cranking and post start up. I've made adjustments to parts of the fuel map to reduce try, but it doesn't seem to have done anything.

I finally have the basemap attached.

 

When did you restab it? I dont remember you saying you did that until now... and the last pic i saw it was off a tooth.

Also about the coolant correction, the map shown above says your water is 0 degrees. so either its really cold where you live or somethings wrong. (edit: or youre in offline mode)

Also you should have your injector settings set to "staging" not "batch".

I dont understand why you just wont try a base map from the haltech section. Just save the one you have, and try it. if it doesnt work, load the other one back in.

 

you need to keep it running until it warms up. if its crazy rich, you should feel free to lean it out a tad while its warming up. for an initial tune, shoot for warm idle about 11.5:1 - 12.2:1, and the rest of the map should be 12:1-13:1.

later once its not crazy rich, you can fine tune it more. tuning the map is a big job, so it helps to break it into smaller chunks

 

I restabbed the CAS last night and got the car to fire. The maps posted above were stills taken off the map when I was charging the battery. That is why the coolant temp isn't registered. I apologize about the confusion regarding that.

As for the injectors, I'm running primary only injection. I will go staged later on when I rebuild. I was told when running this injection, I need to be on batch-fire. As for the other base maps, I've tried them and they won't get the car running.

As mentioned the car is now firing but won't hold idle. I've tried scaling the injectors down on the fuel maps but I'm a bit lost. My injectors are reading around 6-7 ms and my fuel maps don't reflect that. Is there some hidden map I'm missing to scale down the fuel during cranking?

Thanks again for the help everyone.

 

there is some little box you can open that tells you what corrections are going on. i forget what its called, but its in the same menu as the gauges. it lists the injector duty, and what is contributing to it.

top tip: calculate the max duty cycle you are willing to run at high RPM, 85% is a good rule of thumb, and just set the last three high load rows to that number, from about 5000rpm-rev limit. this way you start at the peak duty you're willing to have, and it should be rich, and then you dont need to worry about maxing the injectors out, because they already are. any tuning you need to do should then be making it leaner

you also should load the default map, and then your map, and then resave your map. i don't know why, but the order you open maps matters, at least initially. i would make an analogy to something people do because people are weird, but its more like a dog spinning around so it points north when it poops.

 

How are you disabling the secondary injectors? Doesnt batch mode fire all 4 injectors (Correct me if im wrong please)? That probably doesnt help your rich situation.
