Engine cooling fan - running continuously. I think we might have looked at this before but the green car has been brought back to life and we have a link pnp in it with basically the same set up as the red car. The green (blue) car is a pre face lift model and the red car a face lift model. As mentioned the problem is the engine cooling fan running continuously and I think this might have to do with the air conditioning pressure sensor being removed and in a standard car the default is turn the high speed fan on. in the ecu set up currently I have An volt 9 turned off. May this stage I have just dumped the red cars program into the ecu of the green (blue car) car fyi in the red car (facelift) fan works as expected. I think I gave up before and out a manual switch in but this time I’d like to resolve through ecu any help on this one would be appreciated.

Thanks for such a quick response and info. I’ll look at it when next at the car. again cheers

Hi I’ve got my ECU connected to the MXL Pista dash and it reads temp, TPS, wide band etc but neither of the pressure sensor I have running to ECU are coming thru on the Can. I know the pressure sensors are working on the ECU as I can see them and also see them change values but if I set up on the dash I only see OILP and FUEP and no values. Any help is appreciated. cheers.

So Santa did me a big one on this and delivered a spanking C125 logger for the build. So maybe in a months time ill be looking to set this up. Keep you posted

Hey Adam, ok so a C125 will talk no troubles. Ok, so an MXP or a C125, I'll need to talk to Santa. And thanks

I'm back and since the green car was totaled at Philip Island earlier in the year the Link ECU has been sitting in a box. Re-shelling at moment and thinking about a new dash and the first and easiest choice is a AIM / LINK MXS or MXP running off the canbus but my other Mini runs Motec ECu with a C125 dash, so wondering if a C125 can receive info from the Iink via Canbus like the AIMs? Cheers

PWM for electric water pump. Ok, thinking of changing the electric water pump from an ON all the time to a PWM set up so I can control water temp with a solid state relay, rather an taping the front of the car off. Rather than wiring in something new I was thinking of utilising some of the obsolete OEM wiring and relays with the ECU i.e. air conditioning clutch control. I have seen SSR direct replacements for standard relays and was thinking of putting on of these in the fuse box for the air con clutch , finding the wiring that use to go to the air con compress and wire into my water pump. Logical, feasible? Cheers

Hey Adam Yep, I used that little search engine and think I got what you wanted initially. I will email to you??? If you need more, I will do the add all as you suggested.

Hey Adam Ok, I do not see all your requested items to log under E-Throttle 1 I have the following listed under E-Throttle 1 (Thorttle Postion Sensor E Throttle Target 1 E- Throttle 1 Motor DC E-Throttle 1 ISC Offset E-Throttle 1 Base Target E-Throttle 1 Active Table E-Throttle ISC CL Trim Gear Shift Throttle Target Should I be looking somewhere else for you logging paramaters?

Ok, I will try to do this later this afternoon. After this I will try to do a week session at the track, maybe tomorrow or Friday so we can try t nut it out during business hours.

For the logging have it on set up and when finished put in back to On?

Do i need the E-throttle ON set up mode - on or ON?

Thanks Adam, funny as it hasnt shown this problem for mkst the year if a set up Just been on the dyno and obviously didnt see anything there and can drive in car park but the moment i set tyres on the track BAMMMM limp mode lol I can run the car in the workshop and even run in gear on stands for logs if you like Ill look at it tomorrow Cheers

Wasted a day at the track with constant TPS fault 75 Tried to calibrate, didnt make any difference Tried to simulate in the car park but could get it to fault, so murphys law it happens within 200 metre of going on track No full throttle at by this stage on track, more like a constant 25% with light application with cold slicks. I had this ince before at sandown but it ssems to clear itself eventually, plus i could reset without PC. Power off - on but not this time Any ideas? Thinking of changing tnrottle body but wanted to confirm this fault is totally related to throttle bodyy blade and sensors within? Cheers

Hi Adam Ok, cant leave DI7 sitting all lonesome. I will use that. Cheers

Thanks Adam Would any of the other spare old sensor wires work also i.e. either of the old narrow band 02 sensors, fuel vapor purge valve ETC. Either way I have the expansion cable as the fall back. Cheers.

Just putting a new fuel system in and this will include a FlexFuel Sensor, so presuming this will require a digital input on the expansion cable? Yes

Found the problem and it was a vacuum leak. A BIG Vacuum Leak!!!!! Some large cracks and pieces missing from a near new intercooler will do that. Thanks for you help.

Emailed base map and logs to tech support

Hey Adam fyi does it from cold start now also, so not sure if that makes a difference. Is this his base position something that can change on its own? the log is required while running? just reluctant to stat and moment as 4,000 RPM warm up idle is not ideal but if it has to be done then it has to be done.

Ok, car has been going good but have come across a problem I am not sure if it is ECU related more a mechanical issue. So all of a sudden the car will not idle below 2,000 RPM when warmed up. Prior when cold it might have been a little erratic and idle high with some hunting but still below 2,000 RPM. Had the thought it might be a vacuum leak and this may still be the case but now the care goes straight to 4,000 RPM or more, I turned it off before causing myself more troubles. As I say it could still be a vacuum leak but wondering if anything in the ECU / tune could cause this sort of problem? I can confirm the DBW throttle plate is closed, as I removed the feed pipe to check. Anyhow, if you have any ideas if the ECU / Tune could be doing this it would be appreciated. I will pull things down to look for leaks, as it is difficult to fault find with an engine at 4,000 RPM. Oh, the car drives on the track ok. It is not like a stuck throttle. Cheers

I could give it a go and see if scrutineering will let it happen. This is what is sounds like

Hey Adam This page talks about PC logging, this is not possible as the problem happens on track so I am presuming ECU logging is the way to go?

I did turn logging on while at track so see what I have and will watch the instructional video. Cheers

Ok cars running pretty well, 201 atwkw and only 14 psi Track only car and since new engine with new tune i have quite a hestication on gear change, transition off and on throttle Understand this is accel pump where it goes super rich when i jump back on the gas Looking for ideas to try to fix this while at track as this problem cannot be solved on hub dyno Cheers
