Alright man I'll upload a video for you guys this afternoon. I think the problem is just the timing. Marcauxa1 has a slightly more aggressive tune. It idles pretty good but the afr is just a bit lean. I'll try pulling a degree of timing in the idle load area. Thanks for your input guys, especially marcauxa1. 👍

 

The afr has nothing to do with the timing man :P I can assure you a lean idle is nothing to worry about...you could run an afr of 20 at idle and it would not cause any problems besides having better fuel economy than running at 14.7.....the only thing would either be your injector latency, scaling or voltage. Try raising your injector scaling a bit and see if it helps. As i said multiple times already...a lean idle is nothing to worry about so you could leave it like that unless it stalls at idle! Drive your car and see if your afr is at 14-15 when cruising and if you want to boost you can try a WOT pull and see if it's in the 10-11 afr. If the WOT and cruise afrs are fine then you can drive it normally and boost even more when you install your 440cc injectors and feel what 10 psi is like on the lancer

 

Update!!!!! Lean issues are still there while driving. I just got my bumper back on. I'm uploading the video now. Also.......... My tactrix cable is messed up!!!!!!!!!!! The wires in the USB part must be loose. I barely managed to upload the revisions to my ecu. I don't want to attempt it again. I might brick my ecu. So I'll need to order another cable. I did manage to hit 1-2 pounds of pressure. The slow knock (3 counts) light went off once. It was super lean in boost and cruising. I'm beginning to think it may be a closed loop problem? Feeling the boost kick in and hearing the bov was awesome.

 

Also another note. When the car warmed up while I was driving I felt like it had a hard time going into boost. I think it's the fuel issue though. Video coming of my idle.

 

Like we said. Put the wrx injectors in and test his rom out. Then we can go from there to fine tune it. I highly doubt it will be 100% dead on, but it should be close enough to do a couple logs and upload them for us to check out

 

I'm trying to upload a log of the idle issue but it won't let me. Sooooo currently I won't be able to log or write to the ecu with the tactrix cable I have. I don't even want to attempt to write to my ecu's rom with that cable. I'd really hate to brick my ecu. The only issue with the car is the lean issue. Its lean at idle and when driving. Watching my wideband when I was cruising I was around 18+ AFR. The timing seemed to be good. I only got one low count of knock. Oooo I also went thru the periphery's on the 05-07 auto rom Road Spike set up and copied those into my base rom. I just need to flash it. I'll be hopefully ordering another tactrix cable Thursday The video of my car is still uploading.

 

Here's the video!!! This isn't my initial start. Just my lean issue.

 

That's really weird how the afrs are how rich then go lean like that. I would make sure it's wired up properly and all the connections are secured. Also, go over all your couplers and make sure you don't have a leak anywhere. That or a vacuum leak would really mess with idle like that. Once you get the tactrix cable, just flash your stock rom back on and see if the afr is steady at idle. If it is, you know it's the tune. If not, then it's probably a leak somewhere. But don't drive around and boost at all with the stock rom.

 

Will do. I'm guessing it's the tune though. My vacuum is at -22 to -24 at idle. I hit about 2 pounds of boost yesterday and could hear the bov. Bums me out my tactrix I've had for about 3 years finally breaks when I boost!!!!! :/ the lean issue is only there when the engine gets up to temperature which makes me think it's a closed loop problem.

 

I think he changed the injector scalings in my rom thought so he's going to have to reflash mine into his car when he gets his new cable haha

 

Yeah I changed the injector scaling and latencys back to the stock injectors. I suspect it's a closed loop problem. I can build boost up to 4k with no problem. I haven't even did a wot so I think my couples are secure. I've triple checked those. The problem only exists when the car starts to get up to temperature which is why I think it's a closed loop problem. My next steps are to try the rom with the periphery changes and i also changed my injector scaling to 230. My stock rom had them at 240 for some reason. I do think the 04-07 lancers may have a slightly bigger injector because they're different colors than the 02-03 lancers. Damn I wish I didn't have to wait till Thursday (pay day) to order my cable. it's been 4+ years to get where I am now. I can wait a another week for the cable. I'll be sure to get more videos for you guys when I get to driving more.

 

02modlanceroz has a good point about flashing the stock rom back and seeing how it idles. I'll have to swap back my maf as well. I'll try that first when I get another cable.

 

For sure cuz now u have the evo maf with stock injectors....use your stock maf if you're not using the 440ccs....

 

I could also try a forced open to see if it really is a closed loop problem. I'm getting excited about doing some wot pulls. I'm sure this lean issue is a easy fix. I was reading the car uses open loop until the car and o2 sensors get up to operating temp and then it goes into closed loop when those are ready.

 

Changing injectors take like 20 minutes...imo you should just try the 440cc already with my rom and see if it runs fine and if not just swap them back....worth spending 1hr of your time for a chance for less problems
