(Help) Take a look at my ECU MAP's for 4AGTE?

[dave_101]

Thanks for all the replies guy's, it looks like I can data log with the Stinger, so I will make sure to enable the logging before I start tomorrow and will post up the results when I get back.

From all your replies I don't think it's a problem with the MAP's anymore and is more looking like a wiring problem, the mechanic that stuffed it all up had no idea about EMS ECU's and would say hes stuffed up somewhere, just hope it's something simple like the signals coming from the CAS and can be fixed without to much fuss.

Hopefully the data logging helps to point out any other problems as well.

Do you have wiring diagram? If not I have diagram to suit version 2 with inbuilt ignitors, coil drivers, which uses the V3 software. My map is to suit 4age. I had it setup as base map for my 2tg/3t conversion, which haven't had time to finish.
The diagram includes O2 sensor & TPS wiring. If you need I should be able to scan and post for you.

Yeah it's got an LC1 in there, but once again thanks to this bloody mechanic he disconnected it and I don't know how to re-connect it.

I hate to say this, but if you are running a wideband 02 sensor in an exhaust stream with no power to the heater circuit you will damage the sensor. Fingers crossed that has not happened to you. I can assist with re-connecting this is you like? I have wired up many LC1's in the past.

With regards to your setup, I reckon your tune looks average, nothing stands out as being an obvious cause of what you are describing. Your trigger wiring from the crank angle sensor (CAS) is probably incorrectly wired from the sounds of it. It should be wired with screened cable, with the screen earthed at one end ONLY.

You DO need a TPS wired up to get anything sort of practical out of it (tune wise) in my opinion. I mean, its only 3 wires and a plug and it makes so much more difference.

Where in QLD are you located? anywhere near Rockhampton? if so, I may be able to assist you.

Also where in QLD are you & who did this "work" for you ,it may help explain a few things (pm me if you don't want to post the name here)
DO NOT DRIVE THIS CAR HARD AS IT IS
The maps have not been done by someone who knows what they are doing when it comes to tuning,
for example highest fuel demand is at peak torque for starters & obviously not done with the wideband that you allready had in the car or anywhere near a dyno.
the Ign map is no better

I also suggest checking the wiring & cas polarity

Man that would be bloody great if you could do that, it's running a Stinger v2 with that separate igniter, think its either the 2-coil or 4-coil one below.

Thanks heaps for the info man, the LCD screen in the cabin is still showing numbers but it isnt' moving around like it was before, does seem to change every 30sec or so. I do think its possible that there is no power hooked up on the other end, god this mechanic has done a massive number on this car, hes a total prick. Will have a look tomorrow and see if it's something I can hook up myself, think I have the cables in the car, I think they have only dissconnected the stuff in the engine bay.

Noted about the TPS, if I can get this other problem fixed up and the car running somewhat normal before I even look at a tune I will get the TPS hooked up.

Thanks for taking a look at the tune too, glad to know at least I can rule that out by the looks. Yeah after all the replies including yours I think you are right and the trigger wiring from the CAS is all stuffed up, I will still do a very short drive tomorrow and see what the RPM in the ECU is doing and also data log it, that will be the only driving I do and will post up when I get back.

I am located in Brisy, you aren't planning on coming to brisy anytime soon are you?

Thanks Drew, I had a feeling the MAP's in the car were not the ones in it when I dropped it off, I have been waiting for the original owner to try and find me his last MAP's so I could compare, so far no news from him. Pretty sure this place blew two of the AUX ports on the ECU as I had to send it to EMS for repair while the car was there, they blamed it on the previous owner. Not sure if the ECU would have lost it's data from that, but the car was also sitting in their yard for 5-months or more and prob had flat battery as well. All I know is it's not the same car I dropped off.

The only driving I will be doing tomorrow is the one quick test to see what the RPM does on the ECU, after that I think by the sounds of everything I need to find somewhere ASAP that knows what they are doing to fix what these idiots stuffed. I have just PM'ed who it was, will be posting up who did the work once I have a real mechanic confirm what has been stuffed or not, don't want to start bashing names before I have all the facts.

I am going to try and call EMS tomorrow and see if I can find someone in Bris that knows what they are doing, or if any of you know someone you think would be good for me to take her to that knows EMS ECU's I would love to know.

Thanks again everyone for all the replies, been a bloody big help.

Where in brissy are you ? it will help to recomend you to a decent tuner, EMS tuning is not rocket surgery,but the wiring needs to be right before tuning is attempted.

Thanks Drew, I am in Carina but willing to travel.

You know anyone in Bris I could take it to get the wiring sorted out as well?

Just sent you a PM before as well.

[RT40Corona4AGTE]

Hmm I might be coming to Brissy soon actually.....

[dave_101]

Good stuff, let me know if you do, I really need someone to look at this wiring and get it fixed up. I just asked Drew if he would take a look, but if it's not something he wants to do I am going to need someone.

Will be calling EMS tomorrow, but yeah if any of you guys want some paid work and can help me get this mess sorted out it would mean a lot.

I was going to sell this car, but can't in it's current state, if I can get it all good again I might even keep it, but have to get it sorted before I can work that out.

[Shifty]

Don't take your car anywhere but PITS (Matt Spry)... you think you are 'saving' money going elsewhere but often that is not the case.

However, make sure you have sorted any issues that are not related to the tune BEFORE it goes there as he is not a workshop so much as a tuner.

[Drew]

hey Dave,
mapmaker says carina is 33ks from home or 17ks from work,
If RT40 is coming down it looks like wiring fixup party at your place

Matty has a good rep as a tuner but as shifty said is not interested fixing other problems

Thanks Shifty, yeah that's what I am working on now, have too get the wiring sorted out and then a good tune, thanks for a tip map.

Yeah it's no to far at all, just sent a PM to RT40 to see when he is coming down. I did not expect so much help from this thread and will sleep a lot better tonight, thanks again everyone.

Really hope you guy's might be able to come over and we can get her sorted, will wait for RT40's reply and let you know Drew, thanks again man.

[RT40Corona4AGTE]

I will try to let you know ASAP what is going on, work are sending me there sometime apparently so when I know you will know
otherwise, I will provide as much help/advice/etc as I can !!

and nevermind, this is what Toymods is all about!

[RT40Corona4AGTE]

I will PM you my number too mate, feel free to SMS/call whenever, if I dont answer then I am either under a car or asleep. LOL

Sounds great, I really hope you can make it down.

Yeah this forum has been so good to me, so many nice people always willing to help, I am still taken back with the amount of help given tonight on this thread alone, would have been really in the dark without it.

I will PM you my number too mate, feel free to SMS/call whenever, if I dont answer then I am either under a car or asleep. LOL

Thanks for that mate, will try and give you a call tomorrow after I do these tests.

Time for some sleep here, see you all tomorrow.
