I have just finished installing my new engine in my 91 GT. I am having major issues and cannot for the life of me figure it out.

My build:
DART sportsman block
D1SC Procharger with intercooler
SCAT internals
Forged Pistons
MSD dizzy set at 10 BTDC
90 MM Lighting Mass Air
90 MM ACCUFAB TB
mechanical water pump
Aerometer A1000 complete fuel system(Sump, pump, fuel rails, regulator set @40#) with 60# injectors
NJK plugs @ 35
Electric fan
MSD ignition box
TFS racing High port heads
TFS Intake
Super comp long tubes


Here is the issue.
Configured my tune using the tutorials (scalars and functions) on YouTube that was applicable to the 9al tune
http://www.youtube.com/user/tweecer
The car can idle but runs very lean and when you give it throttle it kicks more than a 2 year old leaving Toys-R-Us. It has a searching idle and I have the set screw full just to idle
It also has no vacuum. The lean condition and no vacuum sometimes means a vacuum leak but I have done the starter fluid and tried the cigar trick (smoke) and cannot find a leak( car has no exhaust so I cannot hear one). I did get it up to 2k and there was some vacuum for a brief second. I will be pulling the codes (throws a code a few seconds after the car starts) after this weekend but if anyone has any thoughts please let me know. I can upload my tune and data log if that helps

Thanks,
Lance

Fix the mechanical issues first, then start tuning. If it has no vacuum, then something is wrong. Fix that first.

Once you fix the mechanical issues and get it to run ok you will probably peg the LMAF.

Procharger is designed to be a blow thru set up. Your lmaf is a draw thru meter and will not work. I would recommend a pmas 3" (depending on your tubing configuration) blow thru protube for your set up.

Can you explain what the difference is? The Procharger setup recommends this setup(using a MAF) and I am confused why this will not work? I has the P600 on the stock engine with no problems

Well first of all I assumed you had an intercooler installed on your car. If so then you have to have a blow thru meter. If not intercooled then in theory you can have a draw thru meter but the problem with that is your lmaf will most likely peg or max out as it will only support up to 360-380 hp. Procharger units are designed to be installed on the driver side on fox body cars and 99% of people will run the maf as a blow thru. I have never installed a draw thru or seen anyone use a draw thru with any procharger set ups and I have installed quite a few. The pmas protube is a maf and is designed to be placed in the stock location and meters the air as it is blown thru from the blower. A draw thru meter is the lmaf which gets installed before the blower head unit.

I am running the same intercooler (3 core 3 inch) off of the old SC and was using the stock MAF. Now the engine has completely changed and it seems I bought the wrong MAF.

I am afraid so. But look at it this way, at least you asked before you pushed out a head gasket or worse.

Ok ordered a pmas so that should fix the MAF issue.

Unhooked the lightning MAF and put in the stock one for now. Scan the codes and am getting a 23(TPS) and 56(MAF) and I have some vacuum. The thing is running lean 28-29 on both banks. how do I fatten this up?

I have added my tune and log files.

Thanks for the help

i didnt realize a wideband could read upwards of 28 ish, wouldnt the engine just kill it self cause of lack of fuel around 20sh ?

the 28 is from my O2. I am still tuning in my wideband. it was saying 1 since I didn't change it yet

Fixed the TPS issue and check the MAF and made sure it is working. I think this is a tune issue and it is still running lean. Not as bad as before. I will get a log and attach in a bit. Any ideas on adding fuel? I am still learning this tuning thing .

You can add fuel by the injector slopes and or maf curve by increasing or decreasing the kg/hr values. If you multiply the kg/hr by 1.05 you will be richening by 5%. Multiply by o.95 will lean it 5%. What you are wanting to do is match your afr to whatever your commanding you base open loop lambse to be. Make sure you disable adaptive learning, force open loop and clear the kamrf. Set your injector settings for the 60#'s and multiply the entire maf kg/hr values by say 20% just for the heck of it and see how she responds.

Played around with the MAF transfer and I got only bank one down 10-12 Bank two is still lean and I am 100% confused. I swapped the O2 sensors to make sure it wasn't a bad sensor. here is my latest log.

Also wanted to add I pulled the plugs on 1 and 5 and they were both black (rich) so I am getting mixed signals.

ive never had a problem with blow or draw

sounds like your rockers need to be adjusted

Procharger intercooled supercharger kits are disigned to be used with a blow thru maf set up. I am not ruling our the valve adjustment but draw thru on a intercooled Procharger is a no no.

I have been known to exceed manufacturers recommended design specifications from time to time

So have I, but not knowingly with a Intercooled Procharger. Draw thru just doesnt work. Act temps fluctuate too much between the head unit and intercooler. You will never get the tune right using a draw thru in that configuration.

I couldn't get the thing to run and the rpm would jump to 3k ( this was with the MAF open to air and not using the SC tract).

I have installed the PMAS in the uptube coming from my intercooler and it is idling and it's varies between 13.5 to 14.5 so I'm good to go. I had to order a new BPV valve since the stock Procharger one will not open at 3 inches of vacuum(going with the Big red) and and I had throttle issues(throttle would continue for a few extra seconds after releasing the pedal). The Stock valve would not open and bleed off the extra air. I also had to install a vacuum pump to run my booster.

valves were adjusted to 10 thousands. Thought that was my vacuum issue. The issue was a very lumpy cam with OL .

Good to hear the MAF I recommended worked out for you. I also replaced my stock Procharger bypass with a BigRed when I had that set up; plus I was running 20#s.
