Forgot to say, you can view DeltaDash logs using just the demo version... so any logs done you can keep and view at your leisure

ECU learning codes ( how much it has had to learn ), Injector scaling, MAF scaling, ignition advance and AFR thru the range under different loads...

I have AEM CAIK, and 800 cc injectors, and am curious how the ECU copes after mapping .. we had a "hole" at 3000 - 3500 where gentle throttle gave hesitation / fall of revs before it came in normally.. harder throttle is OK .. think it is some transient closed / open loop thing?

Not that I could understand the ( hex? ) numbers off the displays...

Where are you based Tony, North England IIRC ?

Hmm no idea of my ECU code, STi 330S sept 2009 if that helps.

Thanks

Mine had the same fault but was 2700rpm to 3000rpm on very light throttle application, so it wasn't anything to do with the transition between closed/ open loop modes as that only appears active under heavy acceleration.

If I recall correctly when I had Andy look at mine we just rescaled the maf slightly to eradicate the issue & touch wood it's not come back.

I can't remember how much lighter it was, but it is a LOT lighter than the OE battery. As far as keeping the car going, I once left the car for 6 days, and it was flat, I've left it for 4 days before and it's been fine. So it depends on your usage. You can get a PC680, which is only marginally heavier.

This might not be the same as you guys but i also have an AEM CAIK and i notice with very light throttle between 2500rpm and 3000rpm i get very slight hesitation, but under hard throttle this isn't the case

Have you tried the cars for sale thread!

Cheers Rob, didn't want the worry of the other thread ( ringland failure symptoms !!) in the back of my mind.

Was fine on AEM after remap, but after re-remap after the 800 C injectors ( different mapper / new map ) there was hesitation around say 2800 to 3300 like a hole in the pick up .. not turbo lag. ( shame as if change up gear at around 5k it drops into this hole ).
Had a couple of re-tries, one after I put on a 3 port boost controller, lessened but not cured. Going to see if we can do again.

Goes like stink on mid / full throttle and the "hole" is less on meths mix.

Also a bit kangeroo / hesitant on slight throttle under 3000 and a bit odd on cold start!

As you say we maybe didn't pay enough attention to scaling AEM and to off boost / light throttle performance.

-Shane- have you had your hatch remapped to scale the AEM caik?


But does seem like a slight glitch with mapping in the different MAF scaling the AEM kit needs for it's superior air flows....


Funny thing but Paul666 has same CAIK, same boost controller, 3" scorpion sports cat exhaust ( mine is H&S ) and mapper said his was easier to map!
Of course Paul's is now forged mine is std chocolate pistons ...

With DeltaDash the injector and MAF scalings aren't viewable, however you can log and graph ignition advance, advance multiplier, ignition correction etc. AFR is there but this is from the standard sensor, so more of a guide than an exact reading. Also ignition duty, boost obviously, MAF voltage and flow (may be able to give a guide on scaling) etc. I'll connect to the car tonight if i get time and screen grab all the parameters you can log.

I'm based in Manchester... if anyone in the area wants to check any error codes or do a quick run with DeltaDash to check items or do a road dyno run then give me a shout. I've yet to do a run with my car on the road dyno, got all the parameters bar the frontal area. If anybody knows that can you let me know, otherwise i'll have to get a large print of the dimensions drawing from the catalogue and try to scale off that the area.

Cheers,
Tony.

Do you need to remove the manifold to replace the injectors ?

If so - how long for the manifold off and on ?


And... injectors of choice are the Ecutek 800cc kit - where can I get these at a half decent price ?

They retail at £475 + vat...

Paul666

It's a Cobra 3" just like the ones available in the Group Buy

It took longer to tweek yours than it did to map mine

Paul666

Neil(Vulnax999) got his cheaper than that but can't remember where from. I think he had them fitted without removing the manifold, no doubt he'll be along shortly and let you know.

FYI if anyone is interested in how well your motor is running, you can monitor the Learning Knock Correction values using this utility (and a suitable cable):

Not sure how long it takes or what is involved as I'll be paying a trusted garage to do the work however I just bought a set of Denso 750cc injectors from the states after a very helpful member of here pointed me in the right direction

They work out a lot cheaper than the ecutek injectors and are made by Denso not a UK based mapping company

ahh That will be the company That I used originally and told Neil about then

1 hr to remove the manifold & 15 mins to fit the injectors then about an hr to fit it back together would see the job done, without codgeing cover plates and other bits and pieces

Evenin' all!

Litchfield's fitted my injectors without removing manifold ( n/s AVCS oil feed pipes need undoing to gain access for the injector cover ) but took them over 3 hours to do it ... bit annoying as they charged me by the hour and had said be an hour or two!!!! Was late for my mapping session straight after!

The ECUTeK injectors aren't made BY ECUTeK, they source them ( actually Mitsi EVO 800 cc/min injectors .. not sure which manufacturer tho' ) and make up a fitting kit, I sourced some electrical connectors from USA to save cutting up the wiring loom.

The injectors I got from a mapper - ECUTeK don't ( so they say ) supply to the public, but they were helpful to me as there were no instructions and I initially was going to fit myself.
A mapper I was going to use got them for me £300 plus VAT .. even though by then I wasn't going to be able to use him due to timing.

That's a relief!

Not well!!! Spent a couple of hours on Saturday and all day Sunday measuring, cutting, welding, measuring, cutting, welding . . . . you get the picture. Trial fitted, looking good, only to find that they sit too high - arghhhh!!!!!! What I wasn't able to take into account when measuring was the amount of sag in the base with somebody sitting on it so used best estimate and ended up about 15mm too high. And the real crowning glory is I'd already taken it to the limit so I can't lose that 15mm without a total redesign. Not happy!

Appreciate the 'heads up' on the injectors all.

Did anyone bother with phelonic spacers (if the manifold is coming off) ?

Carl Davey or Grimmspeed do them and claim to reduce temps by 30% approx.

http://www.grimmspeed.com/catalog/pr...hkcr48l882v345


Also thought this thread on NASOIC very good on getting temp under the bonnet down (which is only a good thing).

http://forums.nasioc.com/forums/show....php?t=1841582



LASTLY the slight hesitation on very light throttle application, I feel it sometimes too. Not every day but it lurks there somewhere.

It wasn't there on the filter + airbox, but after fitting the Litchfield / Forge CAIK it appeared. Maybe a trait on CAIK ? In fact off boost it felt so much better on the original filter / airbox.

I did take my car back to have the map tweaked to remove it, but it is very hard to replicate in a test setting. So we fiddled and adjusted and it 'seemed good', but once home for a week I found it again. I'm sure I could take it for another tweak for free but for the time and money I thought I'd wait until another visit.

I've noted what Rob said about how he got rid of this issue - next time I'll know how to literate myself. lol.


Thansk again for all the good tricks that keep rollin in guys

you'll have issues with the blanking of holes in the wings on the hatch, you'll need to blank all the tops of the wing up to as the engine bay shares all the same air as the inner wing, Hence why Stan & myself did the rear engine vent mod on the sides of the car and adjusted the could air feed at the fog light albeit mine looks different to stan's and the intake air temps are 2-3 deg above ambient

Carl Davey ones are found in the Members group buy section...

They have a built in 'O' ring eliminating the need for gaskets.

Rear engine vent mod,

Remove rubber flap

Cut out holes

Yep rear engine vent mod looked like another great idea...

PS what sort of tool cuts out holes like that ?
