Luis Lopez Posted October 13, 2019 Report Share Posted October 13, 2019 Hi guys I’m having some issues with my evo 8. Everyday I have to change my idle setup. And now after a I’m driving coming to a stop it goes crazy like it’s switching between ignition and ignition idle table. And if I turn the ac on sometimes it dies and sometimes it doesn’t. I’ve never seen a car so unstable and inconsistent as far as idle setup goes. I did everything per the manual to setup the open loop idle and close loop. I’m honestly tired of dealing with it and I’m not an expert so I’m asking you guys for some input. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 14, 2019 Report Share Posted October 14, 2019 You havent given any information to allow anybody to help. How about a log and tune file? Quote Link to comment Share on other sites More sharing options...

Luis Lopez Posted October 14, 2019 Author Report Share Posted October 14, 2019 ok so now the idle is a bit better but tps for some reason doesn't go below .6% when idling. I've done several calibrations and its working but I have no idea whats the issue. Now when I'm coming to a stop, rpms starts going from 1800-2200 or so until it reaches a normal idle and stabilizes. I'm gonna attach the new map since i tuned idle with the idle ignition off first then open loop the closed loop. I'm up to the point that I just don't want to drive the car anymore. Like I said before I'm no expert but tuning an idle for this car shouldn't be so damn complicated :(. I'm gonna leave a mod list since the car is mildly modified.

Adamw Posted October 15, 2019 Report Share Posted October 15, 2019 Can you do another log with overrun fuel cut turned off. Quote Link to comment Share on other sites More sharing options...
Luis Lopez Posted October 17, 2019 Author Report Share Posted October 17, 2019 I will Adam as soon I get a chance, I’ve been working and it’s difficult to find time. Quote Link to comment Share on other sites More sharing options...

remski2 Posted October 29, 2019 Report Share Posted October 29, 2019 Assuming your base "idle igntion" is 10deg... Your Idle ignition table seems wrong. It uses actual degrees and does not substract from main ignition table. Quote Link to comment Share on other sites More sharing options...
Luis Lopez Posted October 30, 2019 Author Report Share Posted October 30, 2019 Here you go Adam, log with overrun off and close loop lambda off.

Its not much of a log but it doesnt look to far off working now. A couple of suggestions: In the idle control settings, chjange the AP/TP lockout to 1%. Fix the ignition table and the idle ignition table. Remski's idle ign table above is what I would expect to typically see. For the ignition table I would expect to see numbers around 10deg in the area I have marked pink, and 30-40deg in the area I have marked green (with some blend in between these areas and the surounding cells).

I’ll do that Adamw, the reason those values are all messed up is I tried to idle the car with the idle control off and with 10 degrees of timing the car would idle at almost 2k don’t know why though Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 31, 2019 Report Share Posted October 31, 2019 18 hours ago, Luis Lopez said: with 10 degrees of timing the car would idle at almost 2k don’t know why though That suggests the idle valve is not working or the base position table is not correct. If you put it in open loop made and adjust the idle base position does the idle speed change? Quote Link to comment Share on other sites More sharing options...
Luis Lopez Posted October 31, 2019 Author Report Share Posted October 31, 2019 I’ll check today, I have another iacv here so I’ll swap them if anything Quote Link to comment Share on other sites More sharing options...

Regarding the ignition table, the cells from 0 kpa and lower, are way off... I would copy the base map table and fine tune from there. (0 kpa to -20 kpa @ 4000 rpm to 5000rpm look decent) Quote Link to comment Share on other sites More sharing options...

I’m going to order a set of Nerdtuning knock detection headset. And tune from there Quote Link to comment Share on other sites More sharing options...
