Can you do a base tune for svt393 also? I have not had time to get to his and I may be out of town this weekend on business.........

If so drop me a pm and I will email you the list of modifications that he sent to me by email.

Thanks,
Dale McPeters

thanks i finally got it to idle without the tweecer. i had to wobble out my holes on the tps a littler bigger so i could set my idle at 850rpm and be able to turn it under 1v. when its warmed up its idling. i stuck the tweecer on it and it doesnt want to start when the motor is warm. wtf?

EFIpunk thanks i havent put your tune in yet going to do it right now see if it makes a difference :)

I am sure things have to be adjusted.

I never got that email, but I solved my problem.....I think.

EFIpunk-
If you want to toss together another base tune so I can compare notes here is my setup.

Bone Stock 95 302 (T4M0)
Fox TB Conversion (with stock upper)
70mm TB/EGR spacer
Lucas 42# injectors (39 psi w/ Vacuum off)
Pro-M Univer 3" (Cal'd for Turbo blow through)
255lph pump
B&G Turbo Headers
Precision PT-70 Turbo
Tial 38mm set at 8.75 psi
Kirban AFPR
and initial timing at 10*
running on 92-93 octane

My MAF transfer should be the same one you got from gt40_5.0, since I sent him my flow sheet.

ok i downloaded the software on my laptop and when i cant write or do nothing to the tweecer. Comm Fail it says in the lower left hand side. also when i try to click on calcon a little box comes up says "Invalid varient type conversion" and click OK. wtf is up with that?

gt40_5.0 · Post by **gt40_5.0** » Fri Jun 03, 2005 2:11 pm

nevermind forgot to install the driver doh!

but it still is saying "Invalid varient type conversion" when i try open calcon. but after i click ok calcon comes up.. i can not datalog either or none of the gauges work

Make sure you have the Datalog checked at the bottom of CalEdit before writing to the TwEECer.

Mean92LX · Post by **Mean92LX** » Fri Jun 03, 2005 3:22 pm

Just got it.....Thanks.

I will give it a shot tonight after I get some odds and ends fixed

alright got it working. what should the LAMBSE be at idle? is that just a/f ratio? KAMRF's were at 1.0. still getting some idle surge :( still waiting to get a wideband

EFIpunk · Post by **EFIpunk** » Sat Jun 04, 2005 5:20 pm

lambse is the target AF...should be 14.64. I will send you an update to maybe help the idle surge on sunday.

Mean92LX · Post by **Mean92LX** » Sat Jun 04, 2005 8:27 pm

My lambse is never right to what is in the tables, but my wideband is showing my tune is working great. I wrote my tune sitting at my desk at the office and it is really close to being dead on. I still need to get it on a Dyno to finish it but it has been fun sliding around on the neighborhood streets today.

i'm really having problems today. ok i went to go start my car today and i noticed it was kinda running like shit. had to keep on the gas to keep it running to pull out the garage then it killed. so i thought i ran out of gas..which i probably did. so i went and got more gas and filled up 5 gallons in it and turned the key and the fuel pump wasnt turning on.... so i put a different fuel pump relay on it and the fuel pump turned on but it doesnt want to turn off!! and the car doesnt want to start. while the fuel pump is staying on... under the hood u can hear like air or fuel or something flowing under there and its pretty loud. i dont know what the hell it is! i think its flooded out from the fuel pump staying on while the key is turning on and pump keeps pumping but i dont smell too much fuel. i try to crank it and it doesnt even want to even try to start it just keeps turning over. i am getting fire also. i pulled one of my plugs out to see if it was wet and it wasnt..but that was just one. u think one of my injectors is stuck open or something or maybe the fuel pressure regulator is out? im confused. this is the 3rd time i ran out of gas in it just having it running in the shop fooling with stuff and trying to tune it. i know that isnt good for the pump. any ideas?

even with the tweecer pulled out and it running on stock ecu it still does this. thing was running just fine 2 days ago..

EFIpunk · Post by **EFIpunk** » Tue Jun 07, 2005 11:48 am

does it start if you hold it to the floor?

gt40_5.0 · Post by **gt40_5.0** » Tue Jun 07, 2005 12:46 pm

nope it just keeps turning over doesnt even try to start...going to see if my injectors are even pulsing..if not might be a bad ignition module ??

gt40_5.0 · Post by **gt40_5.0** » Tue Jun 07, 2005 2:14 pm

well i just put a test light on one of the injector plugs and i am not getting a pulse at all. i switched ignition modules with another guy with a msd distibutor and still no injector pulse. I also checked it with a mulitmeter and i am getting no voltage to injector plugs at all and no voltage at all to the tps sensor with the key on... ecu toast?

gt40_5.0 · Post by **gt40_5.0** » Tue Jun 07, 2005 4:58 pm

yah i found the problem :( my ecu is burned up!!

gt40_5.0 · Post by **gt40_5.0** » Wed Jun 08, 2005 3:59 pm

and also not only is the ecu burned up the but tweecer also. :(

on the bottom of the circuit board with the port that plugs in the ecu a component is glowing red and melted. its has Q1 labeled next to it. anybody know what that is? i can replace it. i know its some kind of transistor but i need to know the part #

another base tune?
