I started having a weird problem yesterday, I noticed on decel the Lambda 1 reading displays 0.000 after a couple seconds. The car runs fine and displays 10.1 lambda for the first couple seconds then its like it shuts down. As soon as throttle is pressed it reads normal again. The Can Lambda kit is just under 12 months old. I've attachted a log from my drive yesterday can lam test.llg

What would need to be alter on the board..I also am interested .

I'll have to look into that. I did not know the dash cluster had a speed signal out. It uses a cable from the gearbox.

I have a 1990 VR4 Galant with the VR4Link P&P ecu. I am having trouble with my speed signal. I have it set up to DI 3 ( FL wheel ) . The VR4 uses the front ABS ring for the signal. The signal is very erratic. Any help would be great . speed signal.llg

Oh really. Do they clog up? Myself and a few mates have been using them for years.

This the deadtime table i used for my bosch 2200 short body 14mm hi z injectors.

Thank you very. I suspected it could be done . Ill now buy a switch and wire up.. Haltechs instructions show the values of each switch point. So I should set up x axis with these values.

I thinking about using the haltech rotary trim switch for boost control. From my understanding it uses the 5v source and gives different signal voltage for each of the 12 switch points. Has anyone used this with success. Im wonder if a 3d table configured with rpm and an ANV input to control solenoid duty cycle should work. Is this posible. Im not after 12 settings but 3 woud nice. wastegate pressure , mid boost and highboost.

Awesome thanks. Ill enter that in tonight..

Thanks Adamw and cj. I found that link but it woud not open. Said it was unavailable. Can i just go to the base map for the car that runs the 1ZZ/1NZ engine and copy the dwell table and paste into my setup? I havent started the car with the can lambda installed as it needs to tuned. I have started the setup stage and will crank over once the car is moved from home. The car will be going straigt to tuner.

Hi , I have the car booked in next week to be tuned and I have a coupe things to finalise. I have fitted a coil on plug set up using the Yaris Denso coils. I after a dwell time table to use. I have also fitted Link Can Lambda and am wondering if I should get reading with engine off? I do as the setup instructs and save, but when i go back into the can setup i cant see the lambda? I put E85 in the tank last night to test ethanol sensor and i got a reading of 90%. I thought this to be weird. Should I be concerned that the reading is higher than 85%? The coil part number - 90919-02240

Awesome. Its a 6 wire Lc1 from memory. I have had it for 10+ years. I just get new sensors every couple years. Ill check the programing. Cool. Ill adjust the trigger offset and put the firing order back to normal. Cool..I have the internal knock turned , the car will be going straight to be tuned once i have everything setup. Thanks for you great advice..

I have the car up and running and i have a few setup questions. VR4link I have an Innovate LC1 that worked fine in the car with the old ecu so for the moment i dont see a need to change. I have wires brown signal wire into AN4 input . I have tried using Lambda 1 and calibration LC1 , but cant get the reading to display on the ecu software. The widenand is working as im getting a reading on the innovate XD16 guage . What do i use for the setup configuration? Question 2 I have changed the orignal coil wasted spark setup to a direct fire coil on plug . The cas has not been removed and car ran fine on old system that was modified stock wasted spark setup. Trigger input could not be altered. I have allocated ign 3 & 4 to the 3rd and 4th coil . I have tested coils independently and each coil corresponds with ecu outputs , but when i started car i would only run when i reversed the firing order. I had to inverse (1 & 4 ) & (2 & 3) , from the default vr4 firing order. I watched the series of videos from the High Performance Academy and remember Andrea mentioning this can happen and you could adjust the crank angle by 360° but can not a setting that has that capability. Question 3 I had the ecu board modified prior to recieving it for the knock sensor modication but have not seen an input allocated to the knock sensor .

Mine is all sorted now with new unlok code. The zero was entered the first time. Is the unlock code the same for ever on each ecu?

I have Bosch 2200cc injectors and I am setting up injectors for moddelled fuel. Do I set up as 2200cc?. My previous system was not desined for injectors so large so I had to set as smaller and adjust deadtimes to suit.

Fantastic. I am going using windows 7. Ill uninstal and load previous version. Thanks.

I have connected my HP Stream tablet to the ecu but cant get my laptop to connect. I get a Com Port error. I go to 'Options - Connections ' and change com port ,but same error. I have checked the device manager and the Link connect has a yellow exclamation mark. I try to update driver but it will not software . I dont know to try next?.

Fantastic . That all makes sense. This system is a little more involving thsn my last system, but so far very happy. Tomorrow is start up day. finger crossed. The setup is a little different than stock. I have removed the coil igniter and have fitted 4 coils run in direct fire setup. The whole harness is new and wired the tacho to Inj5 out. Seems to work great.

Hi there, I have 95% of my wifing setup and had a couple calibration questions. 1 - is there a list of the 'cal' setting for sensors. I have a 250psi pressure sensor for my oil pressure. 2 - a freind has a link pkug in ecu in his evo and said you can set up the tacho sweep feature to display enthanol contenton start up. I checked the tacho setting but can not find where you would set that up. 3 - when i did my map calibration and checked display reading with igntio on but engine off it reads 14.9psi.. How do i correct it back to zero and is the internal 4 bat sensor ( 1 bar negative and 3 bar positive) ?

I have powered my ecu up for the first time and tried to enter the unlock code. It fails and gives me a fault. This isthe message it gives me.

Thanks that some great insite to how it all works. I went over the mpi relay schematics and saw how it works. I will keep it as normal on inj 6 and swap my fuel pump to an AUX trig and use the injec 5 for the tacho. At the moment the AC does not work so ill use that output to drive fans. Ive added some pics of the harness and the coil setup as this is totally different than a stock setup.

I have a couple other questions also. I have removed the power transistor for the factory coils as im going to run a direct fire coil on plug system , so I have lost the factory tacho output and was told to run a relay triggered by ecu ( with contacts removed ) parallel to an Aux output set for tacho to create the voltage needed to drive factory tacho. Do i need to run a resistor inline to the relay coil ground? Also , the AUX settings have a high and low setting . Is this to change between a pos and neg trigger?

Thats great to know. I did suspect something like that as I could not find any info. So it must use either pin 56 or 66 . Ill have to check the mpi relay diagram..Im not using the factory relay any more as I have a custom relay setup. I can just find the pin and wire it to the new relay for the isc to keep it active to reset . Ill just wire fans to the AC trig.

Im in the middle of building a totally new harness for my VR4 with the VR4LINK. I have run out of AUX outputs and wanting to use the Injector 6 output. In the wiring information it mention the output being used for 'ecu hold power' but can not find any information on the pin used for this . Im wanting to use this to run my engine fans..
