Re: s300 hardware problem
well started the car and let it sit till the rad fan to come on and 5 min into it the car dies and when it happens my temps go to 302 again and the rpm goes to 52,427

Re: s300 hardware problem
well im in to the 3rd ecu now .. a chiped p28 ... removed the ic chip and the ic mount .. installed the male pins for the hondata in to the 24 pin slot (27256 - ic4) and the 4 pins (icn2) into the chiped ecu and removed j12
it already had the jumper at j1, resistor at r54 and 74373 ic at ic4
put the hondata in and still no green light at d2
so i pull the hondata out and reinstall the chip back into the ecu by conecting 2 ic mounts together and reconecting j12 the ecu acts normal
pull the chip out and put the hondata back in and 1 green light :(
also traced all conections from the top side of the hondata to all conections on the ic4 (373) and the 66k ic and all where fine ( thanks for the pin out )
also i know its not a bad solder joint as the chip works fine

Re: s300 hardware problem
Out of curiosity have you tried this ECU/s300 in a different vehicle?
It is very strange that this only happens after the fans come on and it gets up to temperature.

Re: s300 hardware problem
yes i tried it in a bone stock 95 integra b18b and my own 95 integra with an h22 swaped and chiped ecu
its not happing when the fan comes on ... that is when the 2nd one stoped working .. now with the 3rd ecu dosent light up d2 at all
but works fine with the chip installed .. infact i drove it into the shop
now you said when you dont get a light at d2 its a conector (solder) problem ... but its fine with the burnt chip so wtf ?
im at a month now with no car to give to the customer .. down 3 ecu's ....
so what do i do now ?
