to make a long story short. is it possible to use low resistance injectors w/o coil box or resistors?
i recently pick up a 99 em1 turbo on e85 w/ rp 88occ tuned on s300. i traced injectors wires all the way to ecu. no box or resistors.

thanks

without a resitorbox low impedance injectors will damage the ECU or better said the transitors with amplify the signal for the injectors.

due to the low impedance it will suck more current, which will damage those transistors.

worst case (and this is usual): f*cked up ECU.

yeah, that's what i've been hearing. i dunno, my car runs fine with those injectors and the previous owner said he used those injectors for the past two years.
i know that on na cars, you need a coil box or resistors to run low res injectors.
i'm wondering if you could use the low res injectors with tuned/compensated on s300 w/o box or resistors.

if it works in your car... fine... but it's not the usual behavior.

the ECU is built from 2 parts, which are parted actually in the middle, where the bar is.

the left side, so the side where the connectors are, is the "analog part", so the part where sensor data is "translated" to digital, which the CPU (that huge IC, which that OKI stamp) in the ECU can manage, which are all on the right side of the ECU.

the S300 (or other products) communicate only with data on the ROM (the S300 simulates that rom in realtime), which is read from the CPU, so that real-time programming is possible etc.

everything on the left side isn't in any form changed by the electronics on the right side. the electrical behavior is and stays the same. only the "translation" and the interpretation of data is changed on the right side.

so, it's probably best to installed a resistor box.
