I just finished instaling the diypnp and the iat and cclt signals bounce from -40 to 170 and the tps start to rise from 0 to 124% slowly and if i push down the micro module it go to -40 and the tps stop climing what can i do? i measure the resistansce from the pin of the module to the pin of the adapter board and all measure less than .02 omms i just don know what to do... help me please!!!!

That sounds to me like something is going on in the wiring, have you double checked all your wiring in the wiring harness?

Have you double checked the grounds, etc?

Is there a variable (potentiometer type) TPS sensor in the car? If not, pull TPS signal pin to ground across a 1k resistor. This will stop the TPS signal float when you don't have a TPS installed.

If you have a variable TPS and it's still floating, then the signal likely isn't making it to the ECU, could be a problem with the jumper wires. Check for the signal with a multimeter while working the throttle, should vary somewhere in the range of 0-5v.

On the CLT/IAT sensor signals-- that sounds like what you might expect if the sensors were disconnected, meaning I suspect again that the jumpers are not correct for the needs of these sensors. With the DIYPNP in place, if you pull the connector off the sensor can you measure 5v on one wire and ground on the other? The sensor's signal wire should put 5v on it, and the other wire should have ground. Wouldn't surprise me if the sensor ground wasn't hooked up to ground inside the DIYPNP, this is often separate on the connector.

ok I will check that tomorow and post the results thanks!!!!!

chango de naranjito

thanks !!!!!!!!! I resolve that problem, but I have a new one, the diypnp do not read rpm, I need to make some moddification to m,ake the dipnp read rpm????

thanks,Frank

how are you trying to trigger it?

Are you using the stock CAS? How is it wired? What settings are you using for the wheel decoder?

I am using the stock cas and is conected like this

1.red wire------ vr +main triger

2.green wire-------vr2 home triger

3.silver shield wire-----main and home triger white and white and black

and setings are the same in the Aaron's writeh up the rpms dot even move a litle so I think is not noise so, any ideas??

chango de naranjito

thanks !! i resolve the problem was the sensors as you say but if I idle less than 1200 rpms I loose the rpm signal what do you sugest??

Double check the VR potentiometers on all boards. Make sure they're all fully counter clockwise.

the diypnp dont have it but fix it with the help of Russ of DIYAUTOTUNE I just aded the alt-cam resistor to ground but I am not sure of some thing the I am having a misfire on 1 face of a rotor I double cheked everything but I see something strange with the leading it seems to skip 1 shoot it suppose to be even right?

because it fire every 180 degree or not? it fire like this,

1--1------1--1------1--1------

it suppose to be like this right?

1--1--1--1--1--1--1--1--1--1

I am using the 3.0.3n code with the stock coil and the igniter removed in fd mode

Send your msq please.

That's very nice that your misconfiguration repair fixed the problem!

chango de naranjito

yea!!!

chango did you know if somebody is running good # with the ms on a rotary in p.r.

chango de naranjito

I instaled one in a rotary powered Mazda glc 13b pp + nitrous and make 485hp I dont know if some one tried in a rotary other than me.Here all think microtech is the only solution for the rotary...

elturbonitroso

yeah i know everytime i call somebody in p.r they said the same thing (that oldrotech its the **** and bla,bla,bla the records )people think that the oldrotech its the only ecu capable to do the job for the rotary engines with out trying something different.

Why I get 100% duty cycle when I have as req. fuel 10ms and in the ve table 123 with the secondarys on at 5k?

muythaibxr

Secondaries should probably come on sooner? Where is it hitting 100%? In my experience if you turn on the secondaries much above 4000 you're going to max out the primaries.

Ken

chango de naranjito

I set everyting as is on the Aaron's writeup but put the secondarys come on by duty when the primarys are above 70% and with all injectors the duty rise to 135%

I have to lower the req-fuel?

muythaibxr

sounds to me like your injectors might be too small.

You should be using whatever gives you the right AFR. If you're maxing out the injectors and the AFR isn't going super-rich, then your injectors are too small, or you have a fuel pressure issue or similar.

Ken

chango de naranjito

I have a stock engine with stock injectors what you recomend?

elturbonitroso

try 35 rpm and 90 kpa

chango de naranjito

ok I will try that and let you know thanks!!

muythaibxr

I'm assuming the secondaries are actually coming on? Can you post a datalog?
