You can flash it with the stock IAT ( keep the maf in place, and plugged ) and revert back so the wife can DD it.

Heck once you install the GM IAT, you still leave the maf there. Kind of practical for tuning anyway.

It works pretty well with the IAT in the maf, just not perfect.

So I have a question. To make avcs heads work, I need the heads, ecu and an ia performance wiring kit. Right? I emailed them today, and the sales department said I needed both of the harnesses. (bulkhead kit and avcs kit) that came out to $400. I thought I needed just the one harness... Was I misinformed?
my car is an 02 wrx ej205.

You need complete heads with the oil lines cams ect. the jdm ecu.
and yes both harnesses. One is the engine harness(since you do not have a jdm one I assume) and the other is the ecu harness.

if u get an engine harness from a jdm car which i reccomend you do then i make an alternativly cheaper avcs harness that uses the stock wrx wiring harness, jdm ecu, heads, and jdm engine harness.

Perhaps I'm missing something, its early still, but it seems like you have too much resolution in the vacuum area of your AVCS maps.

Assuming your atmospheric pressure is somewhere around 14, you would only have about 4 columns of your map for positive relative pressure. You probably cruise at around 9 psi absolute so that would mean in your power avcs map, you cruise, spool and peak your boost @ 40* avcs. I don't think you'd spend much time if the first 4 columns of your map. They would seem to cover idle and just off idle. Is this correct or am I missing something?

You're mileage map example is closer to what I'm running now. I'm working up and down from around 20* avcs at cruise, ramping up quickly starting at loads around 1.2 then tapering down similar to what you have. This seems to have the best off boost response, best spool and great top end. I'm just trying to find the best cruise values now, mainly to maximize efficiency for road trips.

I did some experimenting last night. I used a pretty flat stretch of road with two small bridges at each end to use as start/end points. There was plenty of room to get my speed set coming from either direction. I tested each change in both directions and averaged the results. I tested four different cruise avcs values: 10, 20, 30 and 40. Timing was kept at 48*, average speed was kept at 62 mph, turning 2760 rpms in 6th with the JDM 6MT. I'm running E85 blended at 70% ethanol. My AFR at light cruise loads is 15.6 (gas scale).

10* showed the highest average IDC and lowest average mpg, about 17.7.

20* & 30* were pretty similar. 20 had a lower IDC but 30 showed a higher mpg, around 18.3

40* had a lower IDC than 10* but a lower mpg, around 17.5

I couldn't see any noticeable different in EGTs. They stayed at 1250* for all the tests.

My mpg values assumes that the romraider definition for fuel consumption is correct and that I have fairly accurately created my own formula to account for running E85.

I'm going to work a little more between 20* and 30* to see if I can find the lowest IDC and best mpg and then I will start working on timing at whatever avcs value seems best.
assuming this is true you used the mpg est given thru romraider or did exact fuel calculations?

Hey guys- not really a 207 specific question but anyone with the single piece manifold - do you have an aftermarket turbo inlet? What is it and how does it fit? I'm having stupid issues getting the recirc hose in place.

Thanks!

I got a Perrin full 3" inlet on mine and it fit perfectly fine for me....I also have 8mm phenolic spacers maybe that made the difference?

I have a Perrin V1. It fits OK. Better than it did with TGV's. But still not great. Hardly any fit great though. This one fits as well as an eBay BPM unit for whatever that means.

I'm running the Gimmick piece - my problem is the recirc sits basically between the fuel rails and the manifold and doesn't come away far enough to be able to fit anything in there properly.
A quarter inch and it would be perfect...

He does have a point. Standard deviation on the mpg calculations was between .74 and .87; it was very flat stretch road so the the throttle deltas are very low.

I am just using the RR calculation but I created my own for running E85 to account for E85's different fuel density and to convert the gas AFR to E85 AFR so the correct parts of fuel to air is used. Its probably not perfect but it seems pretty close to what I average with mostly highway driving.

You get one with the Sti pink belt or with the JDM OEM belt.

Not that one. The one on the center timing belt cover that says what kind of engine it is. For example EJ207DW3CR. Mine is coming off and needs replacing.

You get a free engine code sticker free with every purchase of another EJ207!!! Or the other way around, you get a free engine when you buy a JDM EJ207 timing belt cover. Sorry, couldn't resist.

LOL. funny. I have the actual code I just have to figure out how to make a sticker that'll stand up to washing and normal driving. LOL

Twin EJ207s in my Suby would be epic though

You have the proper flash jumper for your chassis harness and your green connectors are not worn out.....Right?
