Pectel T2, megasquirt 2 or vems?
Ok, as a few may know Im currently running a 1.8 zetec turbo (250hp) on a Pectel T2 standalone.
Im in the process of building a bigger power motor circa 400-450hp and am using the 2.0 silvertop in place of the 1.8.
I have worked on an MS install on a friends kits car a couple of years ago and it was easyish to get it up and running as there are loads of base maps already online.
I will need a complete remap with the T2 and I don't know if its easier just to start again with an MS2 or VEMS ? Has anyone got any experience of the pectel software? I cant even get it to run on Win 7 so am going to get XP and try it..
What do people think?

well my experience of megasquirt is ok, if i had the money i would have gone dta and got someone else to map it and save me loads of hassle, but a great learning experience.
all those ecu's will give you good power, it's all the transients that are the deal breakers and no reason to avoid any.
400-450bhp on a zetec turbo does require a fair amount of money though, quite a few hit 350-400 and are drivable. if you feel confident in your mapping skills go for it, i go safe and tune out towards lean to get it where i wanted it, just waiting for a better and bigger turbo now to push on again, hit peak of 29psi and held 26 with current turbo but started smoking.
ultimately go for what you want to work with, megasquirt can be as good as any other if it's been built properly.

If you want a MS ECU buy it from here http://www.boostmonkey.co.uk/ they are all built using a pick and place machine onto a improved custom board and are like OEM quality!

Looks like I will stick with Pectel then, or go for DTA, Haltech or Autronic if I absolutely have to in the future.
Just gotta get the pectel software working and see if I can tweak the tune a lot...
Will be a fun time anyway Im sure

Well, Im planning on sticking with my Pectel for now, seeing as I've got it and they do the job required,
Im going to try and get a decent basemap sorted and then take it to someone nearby (south Yorkshire) to have it mapped...
Does anyone know anyone good with Pectels around here?

A nice spec gt2876 is capable of that at around 30-32 psi...
A gt30 or gtx30 would see you at 450 at around 1.5 - 1.7 bar..?

Having said that a T04b might be on the cards and that would also do the job

There are a few to choose from for that power band, I have been looking to break 400bhp on my tuned Zetec turbo setup, I've decided to go with the gt3071r on a 0.63 housing.
I had a t04b and although it did well, it didn't last long. But it was relatively cheap.
Wilky can do a t38 for a very good price, that will get good power, although laggier.

I will have to be carefull what i say from now by the looks of it as power mad mods seem to like giving me infractions (specialist RS) to name the one!
If you go with a garett gt/gtx then you know you getting the best imo... Reliable and quick spool,
More money but it works and does the job.... And does it well...
I take it your pectel T2 is unlocked?
Have you thought about a spec for your engine?

Thats intersting to know about the T04b...
Any idea how much the t38s are? I don't mind a little bit more lag, might be a goer that one if they are cheap enough..!!
Current spec of the engine is
Zetec 2 litre silver top
heavy duty valve springs and mild port/polish
Forged pistons and Conrods
the current oil pump thats on the 60k engine, the oem ford one
ARP bolts on the mains and conrods
stock headgasket
Compression ratio of around 8.5:1
New big end bearings and mains
fleabay exhaust manifold
Fiesta RS HO inlet manifold
55lb or 80lb injectors depending
Turbo - to suit
Pectel T2
I know the HO inlet mani might not be up to the job, if so I will need to get something else

think I will go for the 83lb'ers based on that advice.
thanks mate
& cheers Rollinz. Sounds like the 83lbers will fit nicely with my goals. Hopefully tuning a decent idle wont be too testy..!

i'm on laptop now, so i can reply fully.
basically i had a ceramic ball baring turbo from unknown origin, i doubt it was a turbonetics, but maybe a copy. now it failed more than likely due to the oil seals being blown open by too much oil pressure as it didn't say to fit a restrictor.
that said i was talking to a turbo re-builder who basically said it wouldn't have lasted long on 2BAR, if it would last down the road at all.
the cheap t3/t4 lasted 4 months and 500 miles max before seals started to go.
gt3071r hasn't been fitted, but did make almost 420bhp on a zetec turbo setup and has done a few pod runs and just general mad driving without issue.
onto injectors, if you go too big you will have to raise the idle to keep it stable, not an issue if you plan on abusing it lots otherwise though. even though my duty is getting high on the 60lb/630cc's i can raise fuel pressure to increase output to 900cc at 6BAR. the problem with this is that my fuel pump can only provide a pressure of 8BAR and 200lph, so a peak of 2BAR boost, not a big issue and a work around the injectors not being bigger, the main reason i got them in the first place.
back to the ecu thing, totally up to your mapper or your wallet, nothing wrong with megasquirt, good interpolation between load sites, good processors on the ms2 or ms3.
the only issue is with build quality if diy and the mapper.

Got to agree with injecotr size with you whisky
However....
I have found the 83lb injectors to be very very controlable at idle,
I can maintain a 14.7 afr at 1100rpm (not too high imo)
I do have a rich spot when coming down towards the idle which we cant seem to sort out, but its nothing im conserned with at all
It basically hovers around a 12 for 4-5 seconds when wyou pull up at a set of lights for example

my 63lbs go a little rich when approaching idle for a short period, if i pull fuel out that stops but revs drop very low. not sure what that is, but they idle around 850-900rpm with a stoich afr, higher idle of 1000rpm is very stable, but the noise get on my tits round town.
going off your target power how about middle ground of 72lb ones instead, plenty of head room and will aid with better idle at lower rpm.
oh and HO inlets are fine, i run one, no back to back testing but doesn't seem like i have to cram in boost to get more out of it.

cheers mate.
Im going with the 83lbers I think, to give me some headroom if I need it..!
Sticking with my pectel, seeing as Ive already got it, and it works nicely. Not sure who will do the final mapping. I'm getting a wideband O2 with logging so I hope to get it mapped to a safe state myself.
@ Rollinz - cheers!
