    Dart iron eagle or ported 193?

    It almost seems like a no brainer. but pros and cons and cost. I have a set a ported 193, dropped them off at machine shop for a valve job and maybe one seat I nicked. I should hear back from them in a few days, on actual cost. quick estimate was about $500 or under. A local guy races super...

    Almost assembled motor, what bin file for start up?

    I did open the port. but only to the factory fuel atomization ridge... so probably only a bit past the 92%. Dont forget this type of port is very different than than a straight through flow type port that most people play with, its designed to swirl half the port at certain lifts. At low lifts...

    TBI / ECM tuning options. Chip / Burn / etc.

    Agreed on many points. I had "self learn" in quotations as it self populates the spread sheet/table, very similar to the method you need to tune either way. At least for my purpose/application, I dont have the need or want to change any of the stock trans functions. shift points..etc. so ...

    TBI / ECM tuning options. Chip / Burn / etc.

    Yup, i really wish it would control the trans functions as well, an All in one package. I haven't decided on what route yet. I needed to find out the actual method, wiring diagrams and the pin swapping first. Its really not that complicated to install, but no idea how both computers will like...

    TBI / ECM tuning options. Chip / Burn / etc.

    I am on the very same journey. 1995 5.7 with the 4l60e ,stock 4727 computer. I had a long chat with Rbob- owner of dynamic-efi, last week. Using his EBL - Flash-II computer to control the engine, and splicing a few sensor wires ,the second stock computer can run the transsmission. Pros to...

    EBL-flash and 4L60E control?

    I wouldnt be making power in that range... tbi even with the LT1 cam would stop making power at 5k. so the stock shift points would be more than fine, no need to modify them.

    EBL-flash and 4L60E control?

    the ability to Tune the engine; because of the heavily ported 193 heads, ported 3704 intake, flattops, 15psi fuel spring, and cam is being changed most likley will not play nice with the stock computer programing. (either a rv cam(summet 1102)- or a melling 1336 (lt1 clone)- haven't decided...

    EBL-flash and 4L60E control?

    yes, the second computer that was written, although not completely clear. I need to use the stock computer to control the stock 4l60E. the ebl modified computer controls the engine. 2 different computers. I should Add its 95 TBI, stock computer, stock trans ( aside from a few internal...

    Help vortec head swap engine doesnt run right

    L31Max- I know you have done the ported tbi heads a long time ago. Would the increased fuel pressure ( pump-spring) be enough for the stock tbi computer to make it run ok on ported tbi heads/ vortec heads? Or would the overall increased fuel , be too rich at idle and not enough at higher...

    Help vortec head swap engine doesnt run right

    I'm interested is this, as im about to do something similar. ( heavily ported tbi heads that should flow close to vortecs and either the LT1 or good old rv cam) What fuel pressure do you have? fuel pump, fuel pressure spring? have you deleted the EGR? And EBL-flash tuning i believe would be...

    cutting down the valve guides- now springs are too big

    So I have bought the spring cups and summits spring kit to match the cam- ment for older Gen1 heads. .490 lift summit springs with the inner damper measure a inside diameter .774", the TBI spring base is .761" Its a much better fit but the springs are still a bit loose. The TBI's set up...
