work past where your map sensor ran out of capabilities (10psi and above and tune from there)

hmmm. no input, answers or suggestions from any of the folks that make this stuff?

Ah that may be part of the problem then. Did you modify the ecu to be able to use D10? You need to find the resistors on the ecu board labelled R136 R137 R138, and cut or remove R136 and R138, which are the outer resistors. R137 is the one in the middle and needs to stay attached. They are located ...

I think you're using the wrong parameters in smanager then. There is not any pre-select choices for wideband voltage settings in Smanager. You have to manually enter the voltage and afr/lamba values. default is 0v-5v-5v and 10.0-20.0-20.0afr, which iirc is not what PLX uses. Crome has a pre-select ...

I've never had any "off-limits" values in the afr offset before. That is odd. What concerns me though is 0.01v difference in offset is causing a 0.4 difference in afr reading. That is HUGE! And next to impossible. Makes me think you have several problems going on: bad wideband ground, terrible prog...

I have two issues: 1) Is it normal for the Smanager software to NOT allow you to define a specific parameter in the program? I ask because I'm trying to set up my injector deadtimes and when i enter a whole number for the volts, the program changes it. Example: I enter "10" and the program changes i...

Can the s300 be used with the Glowshift 7 color wideband gauges and if so, what setting would have to be used?

Are we still waiting?? Also, can we add a feature to the mobile app that allows for changes to be made to the parameters from the app as opposed to having to break out the laptop every time? That would be beyond awesome!

what about the scalar for the omnipower 3 bar map sensors?

well, I would have said the same thing. If the ECU works fine in one car, and not the other, then it's not the ECU...it's something in the vehicle...

I don't know... That's a question for a moderator... But I believe they charge like $50 just to look at it... Before they tell u if its repairable or not :-/

I had the same problem...I was advised by Hondata to just buy a new ECU

search under the s300 calibrations on here for one that looks like it would work for you. people upload and share calibrations all the time.

damn! they steal Hondas over there too? Sorry to hear

yeah...its the ecu...same thing happened to me.i'd have to wait like 10-15 mins and then the fuel pump would prime and the engine light would go off, and the car would be able to start....i suggest buying another one from hamotorsports. they offer money back guarantee on their ecus, unlike some "OTH...
