Rb Wont Start With Haltech For Some Reason

[stricnynel0s]

try going up from 10 in steps of say 5%, and see if it gets better or worse as you go. If there isn't enough fuel, it just won't start, not going to hurt it

aight i will start with 5 and go up from there, did you see any descrpencies with my fuel map ?

[sav man]

give this map a try, i found some specs on your injectors, and used the data to make the deat time table

nope nothing, it started up put like i said it dies immediately after starting, once or twice it will rev up to like 3000 rpm but it still cuts off right after

ok i looked at this a haltech map i had from one of their workers and their ign trigger angles values are differant from mine, and this website has COMPLETELY differant values

which one should i go with

[sav man]

that link has the same settings that ship with the base map. which is the same as the map i sent you. What are the ones you got from Haltech? can you get it to idle if you give it a little throttle?

what was the old ecu you ran, do you have a map off it?

from haltech the only differance is trigger angle is 51 on the gtr map they sent me compared to the 56.5 i have entered. that link has differences in the map you sent me mainly the falling and raising settings for trigger edge and home edge, and dwell time and theyr trigger angle is 55, and i cant get it to idle, just start up and turn right off, even if i give it throttle

my old ecu was a power fc, so no map and it ran injector timing

just for shits and giggles try changing it to 51, also try disabeling the o2 sensor. has anything on the car changed while you did the ecu swap?

ok, i will do that now i am sitting in car, and nothing was changed

[stricnynel0s]

well i went and changed settings to those with your inj deat and still same thing starts up to liek 1000rpm and than cuts off

http://www.mediafire.com/?bzrnxzwmemk this is the latest map, with the trigger settings from that website

I just looked at your log, what the go with the coolent temp, it's all over the place?

If the Log is shoing RPM, the CAS must be working, as that's where the signal comes from. Are you able to log injector ms? so we can see how much fuel it's really trying to put in.

Are you still running the VVT? not that this will stop it from starting, but if your still running it, you will want to enable it once it's going.

Do you have a Air temp sensor?

i do have an airtemp sensor, my coolant temp sensor is weird, it works than sometimes it dosent work, it worked on my old setup, i am going to swap it out with a brand new one i have here. i will see if i can log the injector ms tonight. i am runnint vvt via an external rpm activated switch thats why its not in the map lol

have you made sure the patch harnes, and ecu plugs are in properly?

Do you have a multimeter to test that the coolent temp sensor is coming though the patch harness in the right spot? you should have got a pinout sheet with the PS2000, so you know what pin on the ecu the coolent temp is ment to go into

just posting progress, i am going to log the inj today, and relcalibrate the TPS and coolant, i was told to make over fuel trim -50 and work my way to zero to see if i can get it started, i was also told issue could be inj dead time is on for too long and is flooding intake. i let you guys know how i make out today

[stricnynel0s]

ok i was able to fix TPS issue whooo but still got issue with actually starting car

http://www.mediafire.com/?tm21jry2qth this is a copy of the datalog when i scalled back the fuel map by -75

http://www.mediafire.com/?ynjdwiu5ymo this is the datalog for car with nothing done.

http://www.mediafire.com/?mzzmmmzwkfa this is a copy of the actual map i was using i did the datalog with EVERYTHING you requested.

my other concern is for the trigger settings, ad i have 3 diff maps 2 from haltech with differant settings i ended up using these settings from this site

http://zeplinenterprise.com/240sx/wordpress/?p=308 if you could compare them to your settings it would give us an idea as well

any thing else i can try ?

Start with the basics - disconnect all injectors and remove cas turn cas over by hand with ignition on and make sure your firing order is 153624. If it is put the cas back in to where it was with the PFC. Check timing with timing light adjust cas ref angle in the haltech until the timing matches. Next check that number 1 is firing on comp this should be at 15btdc with cam timing mark not lined up(pointing downwards).eng should now start if plugs are ok

ps - I never use haltech because of triggering issues I've seen with them & unrequested multiple throttle enrichement pulse. Can't comment on the new one tho. Good luck

If you're still having trouble and need expert help, and if you're in Sydney..

TweakiT at Mona Vale are Haltech specialists.

unfortunately i am in the USA, and no one has experience with new haltech thats within an hour. Like i said car will start up for a few seconds than immediately turn off, and i already verified spark and fuel, i did not check to see if its firing in the proper order though i will work on that tonight i am going to recheck my timing for the the 5th time cause i changed the timing settings in the software. for some reason 2 got 2 differant maps form haltech and both of them have differant trigger settings, so i am kinda fubar on that. i researched it and i found settings so i input them which happen to be differant from both the maps i got from haltech, but i have yet to check timing with the new settings so i will go over that today.

[sav man]

which injector des times are you using?

[stricnynel0s]

the ones you gave me

[sav man]

have you got the coolent temp sensor to rear properly yet?
