Is My Car Impossible To Make Faster!?

[jordanlisa69]

Right here is the problem/problems.

1st thing the mods i have are: Big Pod filter, 3inch to 3 and half inch straight through exhaust with 2 resonators and split dump pipe, dsr heavyduty coils, new spark plugs, turbotech boost t. Everything else is standard

So i had the problem of not being able to boost over 10psi with the factory ecu going into R&R. Even when i set it to 7psi it still spikes well over 10psi and is sluggish until it hits the set psi on the boost t, which is weird in itself because it shouldnt be doing that.

So i went and got a mines ecu for my car and it works fine apart from it not liking me boosting over 10psi as well! its not as bad as R&R but has exactly the same feeling. So now i know that it isnt a electronic problem or is it?

My car feels way under powered and sounds like it should be boosting flat out but doesnt move as fast as it sounds.

I thought it could be tired fuel pump or clean the afm?

Tell me what your thoughts are and what i should do?

Everyone please help so i dont end up selling the wee beast.

Well to answer the topic's question, no. Spend some money and reap the rewards. EBC should stop the boost spiking, if that's causing R+R, and/or get a REAL ECU. One that doesn't have R+R, and has to be tuned. It won't be cheap, but will surely be worth it.

Wack it on a dyno to sort out the issue, or get a an aftermarket ecu and then wack it on the dyno. Or even better go to a tuner, talk to them and tell them what power you are after, and they should tell you what types of mods you need. Your wallet will also have to get a bit lighter.....

A fuel cut defender is a cheap way around it too.

[lachlanw]

just sell it . if you were going to buy an ecu and tune it you would have asked about that

you obvoiusly cant be f**ked so just sell it

or expect a big lecture

[jordanlisa69]

ok so about the ecu

its an aftermarket mines ecu so how would it have the restrictions of the standard ecu? and if my car does the same thing on 2 different ecu's then how would another one help?

what would the fuel cut defender do for my car?

I will probly take the car into NZEFI later in the week and get them to see whats going on. but not looking to spend that much more money on this thing. with the mods i have and the ecu it should be around 200kw as is. but i think its more around 140kw as on the factory ecu my best quarter mile time was only 15.5 wtf!

so now you all know how slow my car really is.

and i wana keep it and already looked into spending 2g on a power fc and tune and would be happy to do that. the mines is there because its meant to get more out of my car while i save up for the power fc. but looks like not even a power fc will work atm. trying to figure out if i need to spend heaps more money just to get it to run perfect.

There is more to ecu's than a pfc or a mines. Heres a humungus thread on the VIPEC ecu http://www.skylinesaustralia.com/forums/Pl...ng-t218179.html

There are also several other brands you could go, ie nistune, autronic etc. Do a SEARCH, readup on the forums, go to a tuner and tell them your budget anf your issues, and diagnose your problem.

If your in NZ you could also try a LINK ecu perhaps.

[joeyjoejoejuniorshabadoo]

for a sub 250rwkw an emanage could also do the trick and will cost a few dollars less...

other than that save up and get a pfc

you wont regret it

yea i read up about that but thats alot of money. im just trying to find out why my car is doing this tho because it couldnt be electronic could it? not on 2 completely different ecu's.

First thing I would do if I havent figured out the issue myself would be to take it to a tuner, and get it dynoed, at least then you will see what the car is doing Air/Fuel wise, and boost wise. Then take it from there.

ok sounds good i will pop into the tuner tomo and see what they can do.

mines ecu is just a remapped stocker, it will still do the same R+R when you get towards the end of the map, just not quiet as bad like you said.

buy a real ecu and get it tuned, my pick would be nistune with a z32 ecu.

and realistically, not many 25s make over 200rwkw with the standard turbo, usually around 180-200 depending on the dyno and other mods

I thought I read it all... but what car again???? Also what turbo????

I'm assuming RB20DET? if so with those mods working well i'd expect around 140 - 150 rwkw, not 200rwkw - as the limit is the turbo. (If RB20 + RB25 / VG30 turbo expect around 180 - 200 depending on boost - but again this depends how much boost you want to run due to ceramic and steel wheels in the turbo)

AFAIK the mines ecu will still R & R - it is just a different map to provide better gains to suit a specific setup. The FCD is a cheap option to get around the R & R when running more boost.

If it's RB25DET then with the addition of a FCD and R & R not taking over (regardless of std / mines ecu) i'd expect around 180 - 200rwkw from 10 - 14psi.

At the end of the day, as everyone has said take it to your tuner they should be able to offer cheap options as simple as a HKS FCD and power run with slight tweak to get AFR's decent to the PFC you speak of and Full MAP tune.

get an intercooler

MX5's are nice

[3LGODZILA]

f**k the mines ecu right off to start with its not doing you any favours

Sell the car - you didn't read the advice you got on your last thread or else you would know why the Mines is not doing the job. You should have got EFI to chip the stock ecu and dynotune the car and got yourself a new fuel pump.

If you still have the Mines ecu ask EFI if they can tune it and if not bin it.

not another one...
