OK!! SO!! I reset my ecu via disconnecting the positive battery terminal,, after i reset the ecu the car starts n runs great no problems!!NO CEL,I can see my s300 v2 flashing green n red in the usb port cause it's sending real time stats to my tunerview 2 everything works in perfect harmony,,,,,, UNTIL I turn it off then shit hits the fan!! Car starts runs runs runs 3 seconds then dies,,CEL is on ECU is flashing red with no feed to the tunerview read out just says connecting cause it's not getting any info from the ecu.... NOW HERE'S THE KICKER!! If I reset my ECU it runs perfect again until I turn it off,, BAD CAPACITORS?

What happens if you disconnect the tunerview?

Nothing changes problem stays the same when I unplug the tunerview

What vehicle is this in and what else has been done to this vehicle?

92 civic hb It's currently a B18b with gsr head ,Gsr transmission with a stage 4 six puck Competition clutch, Type R cams, Supertech tt retains, Eagle rods, Wiesco pistons, new crank, new rings and bearings!! Hondata s300 v2, E85, RC1000cc injectors, BRW turbo manifold with gt35r ball bearing, Turbonetics boost controller, Treadstone big intercooler, BWR catch can 4 hose, 255 walbro fuel pump, Tial BOV & 44Mm wastegate, AEM fuel rail and fuel pressure regulator, AEM AFR gauge, Blox 70mm throttle body and Speedfactory 4bar map sensor,

I would recommend that you try our ECU and s300 in a different vehicle and see if the same issue persists.

Ok and if I can't do that what would you suggest I do or try next?

This does not sound like a problem with the ECU or the s300 since you are disconnecting power throughout the entire vehicle when you unplug the battery. This sounds more like something is shorting out somewhere in the car when the key is turned to the on position and that is what is causing the issue. You really need to attempt to try this in another known working vehicle.

So I just read your post on resistor and no resistor spark plugs n it was very informative thx for that post,,and I em currently running non resistor plugs!! Do you think this could be causing my problem with the ecu?

It is a possibility. You should never run non-resistor plugs.

Yeah I caught that!! Well I've changed that since I read that post on spark plugs,, now I'm running resistor plugs n it didn't fix my problem,,so now I'm lost on how to fix my problem?

Would a corrupt file on my tune explain for it?

Create a new calibration and adjust for injector size, then see if that helps. If it is the calibration, import the tables from the old to the new calibration.
