Which adapter are you using with this? I have the app and so far so good.

I reloaded code and it seems to help as its running again. I cant seem to keep comms up. Gonna try a new ignition module tonight and see if it cleans up some more.

Board is cleaned and has been running for the past year. I had some module issues that i thought i had solved. I replaced c22 last spring when I had an injector spike the board. I didnt have my laptop or i would have checked comms. I wont be getting back to the vehicle until Later this evening.

On the way to work this morning I think the ecm corrupted the code. When i try to start it no fuel pump no injectors no lights or anything. v3.0 board ms2 on 2.905 350 with a tpi on it. New relays and have power at ecm. Have a new harness built as well. Was planning cam and head swap this weekend ...

Hey Dave I have a text file is done that way. Most of my factory harness was coded according to the megamanual colors. It has been one of my best diagnostic i have. Im building a new harness for my tpi project.

Im gonna start by relocating my fuel pressure gauge to the whindshield so so i can watch it. I have the all but 1 fitting to temporarly move it. New msd cap and rotor are sitting there as well.

The heads have the 2.02/1.60 in them already and have been cleaned up before. Im not running a specific class with this vehicle but i do want a reliable driver with a little extra pep. I do have head mounted accessories i had planned on swapping brackets and water pump at the time so i could gain ...

Best money i have spent on software. I used the the free version for about an hour before i upgraded. Veal works excellent used it this morning to retune my ve tables and its spot on to what i wanted. Worth what you will pay. The trigger logger with extra code is awesome as well.

Ive picked up about a mile a gallon with careful tuning. Your very well right about the convertor. I checked fluid and its darker than normal. Im gonna pull it out and get it built once i get my other vehicle going. While the trans is out Im gonna cam and head the motor. Changing of tires isnt ...

Ive done some experimenting and still havent got it much better. Gonna start searching other areas of the tune to try and help find some stuff. Ive added timing at cruise and removed a little fuel. Since i swapped to a tpi it seams my ve numbers are about 10 higher than normal No found vaccum leaks ...

Thanks matt Ill check em out.

Guess i better find a dyno close by. do yall dyno and how much an hour?

heres a datalog and tume

Im trying to improve the fuel milage in my daily driver. It get 10-12 on my daily commute and its 10 miles 1 way.

85 GMC S-15 Jimmy
350 sbc stock cam tpi 22lb injectors
th350 2000 stall
31 tall tire 3.43 rear gear
3200lbs with me in it.

Has been at the track alot this season. Convertor seems like ...

I'm in the same situation. 454 chevy with 90 lb/h TBI MS-II. Idles great but bogs when I hit the throttle. I have interpolated the VE tables all the way up to 255 at the top right.

My suspicion is fuel supply related. I'm using an E8153 inline fuel pump which shows 10psi on an inline gauge. I'm ...

I have a diaphram if you need it. I had good sucess with my tpi pump on my tbi unit as well as the others.

You could run an ms1 which is the cheaper of all the setups but also most limited. Ms2 is best value in my opinion cause it does everything that the ms1 does and more plus its only a few bucks more. Im running a ms2 on my daily driver and soon to get a ms3 for the nova.

The open element sensor will withstand the water meth and boost. Ive been using one in my setup with a small shot of NO2. I have a spare i think i could cut on and find out for ya but itll take me a day or so.

Is the original intake in question a professional products? If so It is setup for rear coolant return lines to aid in circulating water from the back of the engine. I run my sensors off the water neck area of the intake. It has a constant coolant flow. Glad to hear you got it figured out as well. :D

Im running the Gm remote mount hei. Stock coil Msd cap and rotor. Msd replaced the cap after I complained about it lasting less than 6 months. :yeah!: Distributor had a failing vr sensor in it as well. The center button is awesome on big cap hei. :lol: I believe Ive got it sorted out alot better ...

Im running the DIYAutoTune mk-hei setup on mine. So far its working flawless. I lowered my cranking timing today and it fires on just a touch more than a bump of the key.
