Mr GRADY.........and all (Tweecer)

[Darek78]

No i don't have any head's yet i'm planing on geting some AFR's 165 or if i get lucky i'm planing on getting a 347 but that is a dream for me now
now i just need to get my car running right
as soon i get a chance i will try messing around with stock maf and slopes and i hope it will work
cuz now i have 19lb slopes on 24lb inj and that damnn C&L and cobra maf transfer and i adv the timing to 14 deg on the global adder and runs ok but still has that dead spot around 3500 RPM like has no power and after that starts tu pull hard again no clue y

Thanks

Derek, nice addition with the sig. It should go without saying, that the first thing you want to do, is get your maf transfer and injector slopes taken care of, then move on to other things.

 

[Darek78]

Thank's to grady for a reminder on that
And for the help to all the people :SNSign: And idea's how to work out my problem ,now i need some time to put my stock maf back on and do some tunning . I will post up my status

Thank's again

Good luck Derek, those sites I gave links to above are EXCELLENT sites for twEECer support. Honestly, they are better than stangnet for twEECer info. Especially EECTuning.org.

I was kinda lost for a while or maybe a more accurate description would be that I was blinded to your combo info in post #11, lol.

With the stock heads in place, there is no way your gonna peg the stock maf.

You could do like Chris & Greg said about using the j4j1 file and moving to your stock maf but keeping your 24's in place.

however

Have you searched for C&L info here? http://eectuning.org/forums/

I'm telling you man, several peeps have made the C&L mafs work on that site.

I'm pretty sure it was you I told about Clint's site.
http://eecanalyzer.webhop.net/
He runs a C&L on his Fox and be sure to use his name in a search on the tuning forum as well.

A little time spent searching for a bit of info is easier than switching mafs if you ask me.

Let us know how you make out with things!

Ok i just got my 24lb injector's installed and i got a C&L 73mm and i put in a calibrated tube orange color ( using a stock maf sensor)
My Q is do i have to change injector slopes on my Tweecer R/T or i can leave it on the 19lb one's????? or it would be better to change them
does the computer think that i'm running 19lb instad of 24lb??????
plus what maf volts should be for the 24lb do i have to change them to??????

Thank's
Derek.N

Dadgummit Derek

I can't seem to stop thinking about what you are trying to do.

Even though I don't know much about C&L maf's .........................

The basic way C&L goes about their cheat method is they use ......

the electronics from their customers stock maf
the different colored cal tube thingys
the inj size supplied by their customer
the pcm values remaining unchanged

Now having said that and since you talk about the orange cal tube ...........

I say this ...... Screw the Tweecer!

and

I ask this ...... How does the car run if you use the C&L in cheat mode?

Ok i got my stock maf back on with the cobra maf transfer and 19lb injector slopes,and it idles pretty good
i will drive the car tomorrow and i will let you know if there is a diffrence in the drivability
when i get some spare time i will try to change the slopes to the 24lb
I hope they will work together
Grady the car with C&L did not wan't to run on the stock setting and when i changed the slopes and left the maf transfer on touched it ran like sh** and wanted to die when i left the stock slopes from 19's did the same thing but after i loaded the cobra maf transfer it ran better
but every time i drove the car and i shut it of for fwe minutes and come back and want to drive it again the car idled like has 4 cylinders and 3 minutes later starded running like it should
but it ran too rich and never pinged with 14 deg timing
i will see what will happen tomorrow and let you's know

Thank's

When you get ready to reinstall your 24's I'd just move over to the j4j1 cal file at that time.

That will make it a real no brainer

btw ... do NOT switch from your stock maf until things get stable.
No sense making things hard on yourself by doing too many things at once if you know what I mean.

Maybe the orange tube is not the correct one.

[Darek78]

Grady so you saying i should keep the maf transfer for the 19 lb inj.....????
and leave the slopes on 19's to?????? and let my 24's run like that ???
the orange tube was the correct one but my EEC dont like it
I will have my reistration code for the EEC analyzer by the and of the week
Let's how big of the help that will be

OK, hear we go!

The whole deal behind all this stuff you're goin through is to find a stable tune.

You said you put your stock maf & inj's back on.

If you did that, you gotta put all inj values you changed for 24's back to the 19 values.

I guess you are running the t4m0?

After all that you may or may not be able to run the cobra maf transfer as there is not a whole lot of difference between them.

I'd run the stock maf transfer so you could then know you got stock everything.

At this point you are NOT looking for max power.
I'd not beat on it with those tiny 19's in there anyway.

Your objective is to find a stable idle and stable closed loop driving conditions. After that is found you can move to making the 24's work like they should.

IMHO, the simple way to get the 24's working correctly is to

1) load in a fresh unmodified j4j1 file in your t4m0 pcm
2) install the 24's using your original gt maf

btw ... dizzy@10 & fuel pressure at stock value

Any Q's ... clear as mud ... or what do you think?

[Darek78]

ok i will try to do it the way you said
i will see how it will work
as of today i droved my car and ran better then with the C&L maf it did not have tha bug down hesitation around 3500 RPM .It pulls hard thru any RPM range
but has a little surge 200 RPM diffrence up and down and after few minutes of driving go's away
that thing never happend with the C&L
Sory Grady but i gon't understand that part ---> dizzy@10<... Timing????
stupid Question i know

thanks
Derek.N

Set the timing at the dizzy to 10* with the spout out.

 

[Darek78]

what's the diffrence with or with out ???
is with out the right way to do it?????

Thanks
Derek.N

 

[final5-0]

what's the diffrence with or with out ???

Spout in ....... pcm controls spark
Spout out ..... pcm is out of the picture

is with out the right way to do it?????

Thanks
Derek.N

Yes

Grady

 

[Darek78]

Thanks.................:SNSign:

 

[Methodical]

It pulls hard thru any RPM range
but has a little surge 200 RPM diffrence up and down and after few minutes of driving go's away....

When I've changed my tunes, particularly the MAF transfer, it takes a bit before idle gets stable. I'd have to drive around for awhile. Give it a little time and see what happens. Peace

 

[Darek78]

Methodical i'm not tuching any thing now
when the weekend comes then i will have time to do any thing
But now i have 19lb slopes on my 24lb and cobra 24lb maf transfer and it runs good and strong and every morning i start the car it has a surge for like 30 sec and go's away and runs normal
but still i want my slopes changed to the 24lb
that's what i'm going to work on this weekend
Thank's

The surging is most likely from running rich still. When I first start mine in the morning, it revs to 1500 for about 10 seconds, then it surges between 900 and 1200 for about 5 more, then settles down to idle. This is the only time it does it however, when I start it later in the day, it just revs to 1500 for about 5 seconds then idles down.

 

[Darek78]

ok here is what happend today i took all you'r advice on setting up the dizzy to 10* with the spout out
Then i read the EEC to get a stock programing on the scalar board i changed my slopes to 24lb inj and saved it and loaded to tweecer
i starded the car and seems to run but when i drive it
it seem's like i'm towing something that has his brakes locked
and buggs down amnit:
after that i loaded the cobra maf transfer to it and act's the same
i just can't get my car to run with the rigt slopes for my 24lb injectors
the best thing i did to have my car to run normal is with 19lb slopes on my 24 pounders and cobra maf transfer this is all done on my stock maf not the C&L
with that way the car runs strong but in the morning has a surge for about 30 sec and settles down
i tryed run every thing stock and still no go
this is a crapola and i think i will try one more time when i get my EA registration code and see if that program will help me get it right
if not i give upppppppppppppp on this

Thanks
Derek.N

You're positive that you have 24's then? Not 19's? I'm not doubting you, just seems odd that it won't run with the 24 slopes.
