So I been looking at 1000cc rc injectors and was thinking of switching over from my 770 sat to peak and hold 1000cc but when I read the FAO under injectors it say I don't really need to use a res. Box and it should pull the same oms but it will be about 2 millsec slower, but here's my q? Do I really neeed a res. box?

 

Yes.

 

You need a resistor box for those injectors if you are still running a Honduh ECU. Some standalones come equipped with injector drivers that can handle low-Z aka peak and hold injectors without a resistor box. The manual for your EMS tells all.

 

Oic, just b/c a local shop here in denver has not been using res box on 1000cc and s300 hondata to tune many 600hp car and and I really don't wanna cut and splice some extra wires but if its more safe I rather have running car instead of a broken car

 

The injector drivers will fail at some point. They aren't rated at ~6 amps continuous operation, and I have the driver spec sheets to back that statement up. I believe there is some current limitation circuitry that protects to some extent, which is why they don't fail outright, but it's like holding your engine against it's revlimiter at 20 psi everywhere you go.

Your car will need retuned with the injector driver box as the injectors will open more slowly with only 1.6 amps dropped across them.

 

How about lower resistance, increase the current to help the injectors out a bit?

 

Listen to Joseph Davis or you will be left wondering why you're leaning out mid range and up top

All the Mistufeces/Honduh/Toyota resistor boxes I've touched were 6.8 ohms. There's a rule of thumb safety factor of 25% with all electronics (except the chinese stuff, apparently) so you could go with a 5 watt resistor, netting around 1.9 amps

Most of those crappy inline RadioSlack resistors you see the kids using can be fit into a stock resistor box enclosure. The resistors you pull out of the OEM boxes are the same things, just have to make sure you get a compatible length for fitment reasons.

 

sounds good! so should some one update this or is it still correct?
