Ok I know I have another thread about the Haltech stuff and I don't to jack anymore threads by accident so I will start my own. Ok problem I have is car no starty. I swapped out my Buschur double pumper and Sparktech cop non cdi for a Bulletproof racing dper and Haltech ign1a coil setup. So about a month ago the car ran ok on old tune with new setup minus what I just added. Had to replace another battery got that in no problems. I decide I wanted to tackle the new stuff I had ordered so I did. Ok here is where the problems exist. I had to pull wires out of the Haltech pnp harness to add wires to my ign1a stuff. Ok great got it all figured out swapped out the dper great it has power it has ground I have fuel. I go to start the car and it cranks but no start. Ok whats the issue here. After a bit of looking into I notice no spark ok fix that, verified I have spark, fuel, and compression ok why isn't the car starting. I call Haltech to see if they can help me with the tune maybe its tune related. Here is where it gets kinda odd.

1) I have no tps sensor at all. I probe around I have power to it I have signal ok replaced. Spent 185 bucks on a new sensor all good to go. Nope still doesn't see the tps and I think I may need a new dvm being mine gives me crazy readings when I try to set the tps.
2) Map sensor reads all kinda positive boost. I have a 5 bar Omni that was scaled per Omni and car read 22 lbs of boost with key on. Ok wtf. Map sensor 2 is an AEM 5 bar sensor that has the ER pnp harness with it scaled to AEMs stuff now it reads 13 lbs of boost with key on. I have been looking all over to see if I have left a ground loose or a bad wire somewhere nothing.

At this point idk wtf to do I have signal at the map sensor, I have 5v both verified by myself and another person on 2 different days. I had to put a ground from the battery neg to my ign1a coils themselves so I can't see that being an issue. That was also per instructions. I have set the dwell time to 4.5 ms to make sure those will have enough spark to fire the car. I am getting tons of fuel and I am flooding the car. I think this is because the car sees 13 lbs of boost key on and not a neg number and when cranking it just adds all that fuel and basically hydrolocks the car on crank. Guys idk what to look for at this point, I don't know what else to do in the Haltech I am stumped. Does anyone have any ideas where to look or even check to see what may cause any of these issues.

The Omni 5 bar setings were as follows
Volts 0.00 4.80
psi/inhg -29.3 58.0

AEM has different settings it has way more but I'm limited to 8 boxes on the Haltech so it goes as follows.
Volts 0.5 4.5
psi/inhg -14.7 60.3

 

Well if you have verified that the signals going into the haltech for TPS and MAP are correct, but the haltech isn't reading them correctly then the issue is with the haltech. If you haven't aready, I would depin the harness for the TPS and MAP signals and check them there at the pins to verify they are correct. Then hook up the haltech without them even there and see what it says. If its still giving some crazy readings then its probably an electrical problem with the ECU.

 

Ok I got my map sensor to read -14.7 I had to switch from avi 9 which for some reason has 1.71v to it and switch it to avi1 idk if that matters or not but avi1 has .4v to it so that falls in the parameters of the AEM sensor. Car still wants to hydrolock full of fuel so back to the drawing board.

Edit: apparently its not suppose to read -14.7 its suppose to read 0 lol wtf back to the drawing board.

 

That is a good idea I will look into that this weekend being I don't have much time during the week being I get up for work at 3 am. The tps right now has 3.14v to it but it isn't set correctly it is around where it should be but idk. I can calabrate the tps with that setting to make it read 0% and 100%.

 

so it ran ok before you had to hack into the harness?
if this is the case... you got something messed up in the harness.

i have seen some of the new - old haltech harnesses will be different.
may get haltech to help and verify pin out.

 

Hutch, I didn't hack into the harness. The harness allows you to pin and depin for easy install of wires etc. Funny thing is I put the car the way it was before all this minus the dper and it still doesn't start and is doing the same thing. I put the sparktech cop back on verified spark, fuel and compression loaded the map back on the car it ran fine off of and wont start. I dont think its anything to do with the wiring to the haltech from the ign. They did send me a pin out chart with the Elite 1500 so I am going off of that, plus the one for the Elite ecu itself.

 

might need to find a good haltech tuner to help trouble shoot.
im at loss

 

Really hard to find in Michigan. There are a few around but I wouldn't consider them good Haltech tuners.

 

So a little update here. I havent made it this far as of yet but I contacted Haltech for some support. Odd thing is they aren't worried about the tps as much as the map sensor which is fine, but oddly enough we repinned the map sensor to a different avi input and whatever voltage is on that avi to start with is what this map sensor is reading. I have looked at the harness to make sure there isn't any cracking or anything it all looks good. I had to verify voltages for the tech guy at Haltech did everything he asked me to do and even he is stumped. I have 1.71 volts on avi 9 and on avi 5 which I repinned the map sensor to it reads like .45 volts and both or those #s do not matter if the sensor is plugged in or not. If you unhook the sensor nothing changes so with that said now I am really stumped. I tried checking for maybe a loose or unhooked ground and cannot find anything. I can honestly say I am stumped.

 

If the ECU cannot read the voltages properly, then you should probably send it into haltech for repair. It could be that the circuitry is damaged. I would obviously contact Haltech first and discuss this with them but I'm afraid that might be where you are at.

 

Yeah i am with you on that. I have tried everything with no luck. I was suppose to have a Haltech tech call me yesterday after work but no go. The guy is an evo guy and he helps do stuck with the dsm and evo guys. I will have to call them Monday and ask them what do I do. I know it will cost me 50 bucks to have them diagnose the problem if there is one. I am just afraid of sending it to them and them being like nope its fine so theres 70 bucks total down the tubes with shipping n all

 

Ok odd change of events. I went out to the car to mess with it and I decided to swap out the ground from my Bulletproof racing dper and put it on the seat screw. Well long story short my voltages from avi9 and 5 the ones I had the map sensors connected to has changed. I reconnected my map sensor to avi9 and voltages went to .23 or .45 I forget but now it reads -14.7 on Haltech psi/inhg meter in the software. Idk if that is good or if I need to keep looking.

 

Well you could try checking your engine to chassis, engine to battery and chassis to battery grounds to make sure they are all good. As well as your battery terminals themselves. You want clean, tight contacts.

 

Battery was low but car still cranked somewhat. I have it charging now but after thinking about it that was the only ground I added and it wasn't in the greatest spot. So I decided to change it. The battery and all the connections are all brand new being the old battery was dead and would not take a charge so I took that opportunity to redo it all. I had to run a pos to the dper and neg directly to the ign coils. So with that said one change in ground and a fully charged battery I will see what the readings say and report back. Biggie thanks for the responses and ideas its much appreciated. Now that I think about it before hitting submit reply Maybe its time to redo all the grounds in the engine bay to make sure they are all good and to cross another need to fix before I get to far into it.

 

no problem, happy to help. Good grounds make everything work well so it's definitely time well spent.
