Anyone have a "fully warm startup log?" here is my latest.. still about 5 seconds of cranking to start. I noticed something weird as well, when i crank the car when cold, and it starts up easy, if i shut the car off right after and try to start it again, it ALREADY starts to hesitate and lagg.. hmm, i dont know what that could be? Here is my latest log, please review it guys if you have some free time, really appreciate it, for you lazy guys here is a screen shot of the log!



Also my MAF values and STARTUP values:

Im also kind of scared to switch back to stock becuase the rom i have is so small, is that how its suppost to be? The tephra rom has SO many options, the stock rom is just fuel, timing, knock sensor, and maf. No startup section, or tephra mods, or trans sections, thats why im nervous to switch back

I'm thinking you can get it, don't give up. One thing I noticed, my startups were worse when it was warmer. It is now colder, so I can't test as much...but I did notice that when I changed one of my maps, forgot the exact name...but you don't have it. It was like Timing map (Warmup???), and it would set my timing to -5 in the "meat" of the low load, cruise and idle section. I increased all of the -5's to 5, and it starts a lot better, as well as cold start driving. I Think you can find the answer, we just have to narrow down what's causing problems. Timing could be a big part of it, too much or too little fuel could, etc etc...but let me hit up the Fred again, and see what he says. He's so busy though, and it's a new rom for him...so, lol, patience is needed I think.

I deff understand about the patience! Yeah that table is the low coolant temp timing trim map or something like that. I do have that table, thanks to 03Lances who put it there for me. i put all zero's in that map. The reason for that map is to pull timing when the motor (coolant temp) is cold and at a certian load, pulling timing in an effort to rapidly increase EGT's to warm up the cat for better efficiancy. I dont have a cat so i changed all the values to zero and now at idle instead of like -8* timing im at around +7/+10* timing.. Should i try increasing the areas in that table to 5 like you have?

At the very least you should see if that 10.75 ms of IPW changes with a couple changes to the startup table.

There are two tables I would be touching to see if they have effect.

Global Fuel Startup - Initial Cranking IPW vs Coolant Temp
Main Fuel Settings - Inject Cranking Primer Enrichment

Try upping the initial cranking ipw and see if those results are come true on the startup.

Timinig doesn't look too bad on startup

I do have a startup log but its on a much colder car only real difference is it started right away with a cranking pulse of 13.5ms.

Oh and just so you guys know its a pretty common issue that warm starts are bad with modified injectors on an evo.

In addition to everything the guru says, try using the attached pictures, and matching them up with your ROM's startup IPW tables. Your current ones (from the last rom of yours i have) are on the right.

Also, the second pic, is Post cranking transient enrichment, put it in for both of your post cranking transient enrichment tables. When I tried what you have, I got the same sensation of having "bigger cams" type feel/sound.

Hey Mitsu, did you ever change injectors out? MAF? all still stock, ya?

Ok, ill go ahead and give that a shot and let you know what happens, ill get it up to about 206*F again and see if anything changes in the log. So the evo's with modded injectors are having trouble as well?? Must just be some fine tuning to be worked out, im sure we can work this warm start issue out, just have to figure out one thing at a time! But ill give that a shot, increasing those tables a bit and see if the log reflects any changes.

Ok, i will try that and report back! Yeah that "cammed" type feel and sound is what happens every time, even when cold, i mean at cold it starts easyer but still stumbles, so ill report back in like 15-20 min!

RS, and hornstar, i have some news. I noticed when i try and change the "IPW vs coolant temp" table, i went from 6.3ms, to 9.3ms, to 16.2ms in the 93*F and higher temps and still the logg only goes as high as 10.75 IPW it hit 11.01 after about 2-3 seconds, then dropped down to 3.58 when it actually started. When cold i can get over 40 IPW, strange.. Give me 2 min ill post a screen shot of the logs, and ill post the actual logs as well... so something is caping the IPW? i have the fuel cap set to 0009 hex wich is to remove the fuel cap in IDC and IPW, when im in boost i get as high as 109% IDC WOT and over 25 IPW.. any ideas??

Pretty strange you guys have problems when stock. The startup code really was never changed you would think it would at least start up and die or some if some of the run time code was screwed up.

Might be an effect of me uncapping the fuel and load limits since it now can behave slightly differently.
