I'm finally getting my vortech tuner kit put on this tuesday. I have the Emanage ultimate installed so they can tune it and hopefully get the target A/F feature to work.

Anyway, I currently have a technosquare ECU flash for all my NA stuff with advanced timing.

My question is should I be ok as long as the emanage ultimate is able pull back the timing? I'm a little concerened because the emanage ultimate still can't set the timing, just adjust it with +/- functions so my ECU is still in control of timing overall with whatever map it decides to go with that day.

would I be ok keeping the flash or should I go to the L-spec, or see if they have a FI/vortech flash available to use for the stock ECU programming just as an extra precaution with the emanage ultimate?

Have you data logged your timing at WOT ? The reason I ask is , that piggy back ECU's delay the timing signal but doesnt show up on a OBD . At WOT my car goes to 22 degree's of advance and advances timing 2 degree's after 6000rpm's . With the SS box in place , Im at 1.5 degree advance less than the ECU has set it at [ with out any changes made in the SS box ]

If you have had your timing advanced by [ say ] 2 degree's . That may be just about right to over come the delay seen with piggy backs ECU . Ithought about advancing my timing in the ECU to over come the delay and help in performance down low . Hope some one else with more know how can answer this for us

 

no i haven't datalogged my timing at WOT.

I've been leaving that up to my shop to do the tuning so I really have no idea what's going on as far as exactly how my timing is set.

I'm just curious if I should leave my ECU with the NA advance timing reflash or flash my ECU back to stock timing or go for reduced/FI timing programmed into the ECU flash itself as a starting point. Then have the emanage ultimate do the rest of the timing adjustments

 

why dont u get a base ecu map change for the vortech, and then use the Emanage to add/subtract to that map?

 

Finally Sentry joins the pack(family)

 

I dont think they can flash the ECU for anything over 8psi . If you have the EMU , that should be better at getting the tune right . I just used the flash for my bigger injectors and used the SS box to tune it

 

hmm.. no, thats not true... . they flashed a TT G35c w/ built motor when it was running 1 bar...

 

sentry,

I would send the ecu back to get the stock timing and fuel tables flashed back. I think they will only charge like $150. Better to be safe than sorry. You can still keep L-spec flash.

 

yeah forgot to mention I'll be running the 440 injectors and a CJM return fuel system.

hmm, well maybe what i'll do is have the kit installed, get the target A/F setup, and get the timing to be really conservative with the emanage ultimate, and just not drive it hard for a week and run 101 octane during this week just to be a little more safe.

After a day or two I'll send in my ECU to get it flashed for the bigger injectors and some timing pulled up top. Then go in and get retuned - probably with the 3.12 pulley at that point to reach hopefully over 400whp. I'm hoping to get around 440 with a 50/50 mix of 91 and 101 octane

 

Don't waste the money to flash your ECU to 440's. You can scale them with the EU. Flashing is only needed for 550's and above with the EU.

 

hmm... if you drive w/o any boost, possibly. but thats hard w/ an SC cuz if u just stomp on it its going to start building positive pressure... the way the NA flash goes is the advancement in timing and a/f changes most drastically occur right after 3k rpms, and then again around 5xxx - to 6xxx..

i wouldnt risk installing the SC and running it around on the NA program. i know Techno has several vortech maps generated already... you should call and talk to Tadashi and see what he says bout running 101...

 

+1

We had ours flashed for 0.8Bar and would boost it to 1Bar with some fuel pressure tweaks.

 

hmm yeah, but it wouldn't hurt anyway though would it?

I'm just thinking for the base map to be as close as possible to being safe in case something weird happened with the emanage ultimate or ECU messing up the timing

 

sentry65,

Since you're already a customer of TS, do the boosted reflash, they should only charge you $150. It really wouldn't hurt, plus you'll have to make much smaller adjustments in EU. Also it gives you protection in case (god forbid) something happens with your EU unit.

 

if you want to be safe as possible. get the ECU tuned as you would regularly for a vortech kit, and if the crap does hit the fan, and your EU fails, you're not risking that much since the maps are already changed for A/F & timing for boost... you're only using EU to get what closer 'more' tuned to your specific setup...

 

yeah but doesn't the emanage ultimate override all that stuff anyway? It should at least have a proper A/F because of the emanage. If it was tuned, it should stay tuned at least to the point of me getting home to pull the ECU out



yeah that's what i'm shooting for

 

I guess it wouldn't hurt, but there isn't any benefit either. If you just flash the injectors you will still have to adjust fuel in the EU. I don't see any benefit to scaling the injectors unless you get the whole Vortech Map which would include fuel tables. BTW is the TS Vortech map set up for stock injectors or do they have another map for people running 440 injectors?

 

Gman2004, they could do either or.
When we flashed for Greddy TT we asked for PE510s tune. Otherwise it would have been for stock RC440s that come with Greddy.

 

I have no idea what maps they have. Just emailed them so we'll see.

I know that AAM has a map exactly like what I'm doing for the UTEC. Been thinking of getting it, but seems like there's a wait right now for it - and it's more money and hassle etc. If the EU is good enough for people to be using on 500+whp turbo cars, it should be good enough for a 400-440whp vortech setup. And the timing fix is coming out last summer err I mean this summer




lol yeah, took long enough. Seems like it's been a long journey in learning things and debating with people etc

 

Just wanted to say congrats on taking the FI plunge. You have a nice setup, you'll have a blast with it and your 3.9 FD....
