[godspeed]

i have a pair of 2.4 bridgeport engines believe to be 88's the ecu boxes are a13s and i have electrical problems w the engines at mid to high speed are these boxes good numbers or should i upgrade any info will be helpfull not knowledeged in efi stuff contact me at vetteguy641@aol.com or post a thread here thanks :confused:

I don't kmow about the ecu's But I would check the injector's ,chances are they are they need to be cleaned

the A-13s are for the latest 2.5 merc drag with SVS intake.cant say for sure if this is causing your probs :confused:

my bp has an a13 ananlog ecu. when my ecu went bad last year it wouldnt even run. mid to high rpm could be coils or i have found when the high side of a stator goes out you can lose over 1000 rpms

i changed the stator already and switched the ecus from one engine to the other i already thought of the high speed coil on the stator for which doesnt let me go over 3000 rpm the engine seems to surge once in a while but all in all it runs bad at high end when i give it full thottle it seems to sound holllow bogs real bad and it seems to run real rich at low speeds and when i start it i hear a small back fire though the tuner hope this helps guys i really appreciate all the replies thanks kevin
