Thank you, I lowered the WGDC% at 5,000RPM so I see 26PSI, and from 6,000RPM i have increased he WGDC to 63% from 60% it is a warmer day on this run so the boost is lower So 3rd gear WOT is from 2,500RPM to 7,000RPM Peak of 26psi at 5,000RPM then tappers to shy of 24psi at 7,000RPM Now my other question is if I am going WOT in 2nd gear to 3rd gear I see higher boost in 3rd close to 26PSi at 7,000RPM - why would this be My concern is if I want 28PSi at 5000RPM in 3rd gear - that it will overboost on colder days Thank you

Thanks, so in hindsight putting more preloaded on the actuator arm could potentially help me, correct? Or changing from a 15psi spring to a 20psi spring

Thank you, I been thinking also that perhaps my wastegate actuator pre load on the arm might be a bit high. Could this cause the spike in psi as the gate isn't opening soon enough? Thank you

I got a built closed deck EJ257 Cosworth engine - 2.6 stroker 81mm crank Cosworth 99.75mm pistons / rods 14mm head studs Cosworth ported heads and Cosworth everything else cams (268 ex & 277 in) springs, etc. Stock location FP Red turbo with an upgraded GTX35 compressor wheel Internal gate with a 15psi spring Invidia Exhaust Q300 exhaust Trying to run 27-28psi however, WGDC% I get a peak of 28psi at 5,000RPM then falls to 24psi by 7,000RPM I don't think I would be running out of turbo creasing on the WOT pull as IAT's are decreasing on the run, is the internal gate struggling and do I need to go with an EWG? I have always noticed this boost trend even when it was tuned for 21psi - I would get 23psi then drop down to 21psi by 7,000RPM #rd gear log attached which is the Virtual dyno picture attached Boost-Increase-Fuel-Fix4.pclr Boost-Increase-Fuel-Fix4 3rd gear pull .llg

Thank you - @remski2 I will look into it and see what's going on here thanks again

Thank you very much @MohammadNaser I will decrease the Accel Enrichment in the 2,000RPM range Re the Deadtimes in 3D I am not that advanced unfortunately Regarding the volt drop this is due to the fan kicking on I think Thanks again for your help it is much appreciated

I am noticing - rich conditions in low load areas example if I am in 4th or 5th gear and accelerate AFR's dip into 11's low 12's I am noticing exhaust fumes while driving if window open One example at 11:50 minutes I could be wrong and the AFR's might be spot on for the load required but correct me if I am wrong please Any tips on helping me make the low load more acceptable or someone willing to remote tune and help that would be much appreciated.

Yeb stock fans, and yes it starts up at around 1,500RPM when cold and the RPM slowly decreases as the ECT increases so all good there

@Adamw I have tried your suggestions and I am still having the same issue Attached adjusted map to your recommendations and log Thank you Adjusted.pclr fans turn on.llg

Thank you @Adamw I will give it a go and let you know! thanks a bunch for the help!!

Hey all, Got a weird situation - car will almost stall when the fans kick on - it has always done this and I am not quite sure why. Could this be tune related? I had attached my Log (happens at 54 seconds) and current map Checked earths on the car and everything seems normal Any help would be much appreciated Thanks

I am having issues with my cold start driving if I need to move the car right after I start it instead of waiting till it fully warms up it wants to choke on it self. I have attached my map and a log of the cold start issue... Hopefully someone can point me to the right direction Thank you,

Thank you @Adamw

I have a question that I am not sure about. When accelerating at a constant speed let say at 60Km and then lifting of the accelerator should the wideband / fuel go lean or rich? I have noticed on E85 it will go rich and sort of hover there. Sometimes it will correct it self and go lean. Example, coming of a highway ramp towards a set of traffic lights I would be driving at 100kmph then coasting towards the lights with out tapping the acceleration and it would be going rich. I notice the same example on my Fuel map and it goes lean while coasting. I want to know if there is something not set up correctly of if this is normal when on E85 Log file - https://www.dropbox.com/s/m6kn080z6w3yrfi/12.5.21.llg?dl=0 Thank you

Thanks @Adamw I will try it out and report back. Thank you for the feedback

I have an issues with cold starts that has always been there since day one after a tune was done. On my Flex tune it doesn't matter if I am running on Petrol or Ethanol it's the same for both scenarios. The issues is the AFR's will dip into the low 10's AFR on the gauge under .7 Lambda which is way to rich and stinks out the garage/surroundings badly. Then it slowly creeps up into the lower 13's AFR till it hits about 80 ECT where it will creep into 14.7 AFR What would be the ideal AFR Target for cold starts and how do I adjust this? Thank you for any feedback as it will be much appreciated.

Thank you @AdamwI will report back once I get to lower Ethanot % thakos for the reply

I have a quick question in relation to Multi Boost Level on variants of Ethanol % Content At 15%+ Ethanol Content, my AFR's are pretty much spot under full load At 11% Ethanol Content, my AFR's are way richer ??? By the looks of things my Wastegate Duty Cycle % are lower on the 11% Ethanol as I would expect it to be Is there a simple explanation for this? Map uploaded Thank you

@Adamw I might have an answer to my problem. When we changed the lambda sensor for some reason it was in my map showing as a Zetronix Z3... Even though I have a AEM X-Series gauge... This is how it was tuned under Zetronix Z3. I have changed to a NEW AEM Lambda Sensor few months ago but never changed the settings in the file to change from Zetronix Z3 to a AEM X-Series as it just worked I have had a play with the settings today and noticed when switching from Zetronix Z3 to AEM X-Series settings the AFR becomes more richer about 2 points richer. Would this mean I would need to have the car retuned if I wanted to switch the settings from Zetronix Z3 to AEM X-Series for example https://www.dropbox.com/s/yh4kyj4qexmoelm/original map AEM 22.llg?dl=0 LOG FILE AEM SETTINGS I am not sure if these two would have an effect on my Lean spike AFR Thank you. I hope the above all makes sense

Thank you @Adamw I appreciate your feedback. I do not know what it might be. I have replaced the Lambda Sensor not that long ago as my old sensor gave up. It fixed allot of other issues that I was experiencing however the new sensor never fixed lean condition.

Thanks @Adamw I have tried to play around with the Accel Clamp Table and I saw no difference. What I did try was switching from FP-Sensor to LOAD=MAP and I have notice an improvement Could this potentially be a faulty Fuel Pressure Sensor giving me this drama with the quick lean spike conditions ?

Hi guys, I have a question in regards to when I stump on the throttle to 100% at lower RPM cruise RPM the Air Fuel will go lean and the car will sometimes stutter then go back to normal. ( I have only been doing this to log and show the data on what its doing) Would this be due to a bad low load VE Table or close loop fueling or Accel Enrichment? If I progressively increase the % of TP it's a lot better Running 1,700cc ID Injectors Attached log and map Thank you https://www.dropbox.com/s/endueqn9by4ofnv/feb 11 v7.llg?dl=0

A new wideband sensor has fixed my issues Thanks for all the feedback. I appreciate it as always. Thanks,

Thanks for the reply. The AEM gauge and Ecu read the same data in this case richer then the Dyno wideband... It's not a case that the AEM gauge is reading different then what the ECU is reading. Both the ECU and AEM gauge read the same
