Go to the post with the logs , I didnt want to open another thread

I was checking out ev8siv3 stage 1 map and trying to copy his open loop closed loop values, but I have diferent tables, and I dont really understand the whole OLCL thing enough to edit it my self.

Could some one check it out plz.

TIA, Stefano

Ok I was comparing stock for stock values in my ROM to the USDM 05 and 02 WRX's, I share identical values for CL with the 02 USDM WRX.

Should I copy the delay values for my 05 wrx from the 05 or 02 Stage 1 OSECU ROM?

I tune for 10% of the original values. So simply drop the last digit (ex. 3000 becomes 300)

Unless you're talking about the RPM table with the 88's across the board up to 3600??

Sorry, my post wasnt very clear.

I was talking about the Closed loop delays, i should just shoot for 10% of all values then.

Just wanted you to know you did this on all cells for the 02 Stage 1 map, with the exception of the first cell that you left stock. Just in case its a mistake

Moving on, how do the throttle tables work, I have the primary that I set at 42% throttle up to 3600rpm, now im lost how the (Maximum) (Sea Level) (High Altitude) tables work & what I should do with them.

Usually I see around 12.94psi as the lowest pressure at the highest point inthe city (3600ft) but I often go to the beach where I logged the normal 14.7 psi. Im guessing that some tables take over at specific Atmospheric pressures so i need some help to get things working at all altitudes at not have my car go crazy sometime when im 2 hours away from home.

I tend not to touch the TPS on 02/03 because they don't have the jerky changeover like the 04/05 cars do. Being that your ECU is for a MY05 you may experience that jerkiness. The changeover is at 3650 rpm so I would set the 3200/3600 tps values to 42 for now and leave the others the same.

I thought I'd changed the first value from 2075 to 207? wierd.

The first value is 366 and you left it like that. This was a mistake?

Anyways, thanks a lot for all the help. Im flashing tonight and i'l post up some logs later.

Oops I better fix that. Change it to 36.

Ok, I flashed two cars with this map.

Mine with the wastegate tightened 1 1/2 turns.
EdgardWRX with the wastegate in the stock position.

Edited: boost comes earlier and there is a improvement in low end torque, i was expecting more of a woa felling with the tune, but although I dont feel it, I managed to pull about 3 cars to the top of third from a stock WRX. Solid map, i like it, there is room for improvement in my car, but its a very good Base map ev8siv3.

Here are some logs for the two cars, does everything seem ok?

Edgards car hit 855 C EGT and was seeing negative ignition timing sometimes between shifts out of these logs.

Hi, im new to the site although ive been reading it a bit some times since blindstuff was getting definitions done for our car. We flashed it last night with a map he copied over from ev8siv3, it felt somewhat faster and smoother, but we had a couple of issues with my car:

1) Im hitting 14.5 as peak boost sometimes in 4th gear, should i tighten the wastegate half to 1 turn or am i risking over boosting?

2) Under heaving driving involving curves up a mountain I hit a max of 885 C EGT, is this value acceptable?

3) Should I worry about the negative values of ignition timing between shifts?

TIA, Edgard.

Edgard,

885C is a bit hot, thats over 1600F here. We need to determine why your car is running so hot in the first place in those upper RPM's. Can you log A/F as well? The boost curve itself looks perfect, it has a very smooth taper, and just needs to be bumped up a bit to the right boost pressures. The Wastegate is delivering the right amount of Duty (if not too much) but it seems like you need to turn the wastegate rod about 1.5-3 turns to get up there.

Your timing curves are SPOT on, and there is no signs of detonation in the log. Negative KC is normal between shifts, no worries there.

Please list your EXACT modifications and upload the EXACT map that you loaded on your car. I will take a look and see if we can figure out whats going on.

I've yet to look at Blindstuff's Logs. The lack of "feelable" power is most likely due to atmospheric conditions being different than here, we may be able to tune around that.

Blindstuff,

Your logs look pretty good as well. It looks like we might be able to run a more aggressive KC table from 3900-4800 RPM to help clean up your boost curve. I need to see your A/F as well. I don't see any issues with detonation in your log either. We just have to get around the Atmospheric hump and I'm sure both of you guys will start running stronger.

Posted the ROM image bellow.

As you can notice i eliminated atmospheric boost compensation in the ranges we are used to seeing around the country, just so that when we go to lower levels, for example the track that is at about 1000ft instead of the 3000ft of Caracas, we dont get crazy boost levels.

Top EGT actually was 855 not 885, stills seems rather high...

We dont have a wideband o2, best we can log A/F ratio is with EcuExplorer

We were seeing negative values in the Igntion time field, not the KC.

Sorry to be such a pain man, hopefully i'l get to learn from this and I wont ask so many questions in the future

Ok, the only modifications in my car so far is an HKS Hi power exhaust, I removed the snorkel (but I dont think it makes such difference, I will install it back promptly)

Well since blindstuff introduced me to RomRaider and ECU flashing, he flashed my car with the same map his car is running currently.

Well it's a relief that you tell me that the ignition timing is okay, yesterday we got kind of scared that the ecu delays some timing during shift.

Edgard is your exhaust cat-back or full turbo back?

Alright I can see where you're getting the crazy wastegate duty cycles from since the map only calls for 79% max, the Wastegate Atmospheric comp is adding the 18.8 (which is why we see about 94-95% in the logs). I'm going to take that out on this revision to see if we can get some more reasonable and consistant logs.

I changed around your fuel tables to be a bit smoother and slightly richer just in case. I rescaled your Ignition correction tables and adjusted the values to try and smooth out the midrange as well. Upped the rev limiter, and adjusted your Closed loop Atmospheric conditions.

Give this one a shot and let me know if it improves. Please log A/F from the front sensor #1.

A few questions then, if we are going to see lower WGDC now that we were seeing before it could lead to lower boost, right? So I would have to tighten the wastegate probably about half a turn more.

Now a question regarding just the theory behind what you did, what did you see in the logs that made you pull some timing between 3200 and 3600 for the loads the car was at most of the time and then add timing from 4000 to 6000?

Edgards exhaust is only a Cat-Back for now.

Im flashing the car later on with this map probably tomorrow night that we are going to the track, we can get some good runs up to 4th and i'l post some logs up.

I really apreciate the help and effort of taking a look at this. Thanx
