haltech ex6 bad?
 

i had installed a haltech e6x on a second gen rx7 and for some reason when secondaries come on the car would bog. on the wideband gauge it shows it stays at 13 which is not too lean under 0psi-5psi but it bogs like the secondaries are not working right. the car just wont rev whether i add fuel or take out fuel. i put an injector tester on the connector itself to see if activates when it should and it pulsates when it should. we just could not figure out the problem so i installed a microtech lt10s got it running and roughly tuned it and the car runs and revs all the to 8500 rpm at 10psi no problem. i thought maybe it had something to do with wiring and/or injectors themselves but it turns out everything is running good with the microtech. i checked out the datalog on the haltech and everything is working the way it should. it just would not work when secondaries came on. does anyone have any experience with this or had this happend to anyone here? this computer will now be tested on a datsun 510 race car and would like to know how else can i troubleshoot the problem if it persists?
