I had my money in hand to buy a Blitz ECU upgrade today and they told me to wait two months while Blitz redesigns it to make it more 'user friendly'.

 

What's the experience with other ECUs? JWT and Mines seem to be out there in numbers. All of the units claim lots but does anyone have some info on how they effect drivability? I ain't gonna do 1.5 bar so I'm not interested in max power, just better all around performance (Blitz SBC-ID, intake, no cats, 1998TT).

Would the Blitz ECU be setup for UK fuel ? If not it's probably better to avoid it. Quite a few people here will have JWT and a few others will have SE, there will even be a couple of MINES. I *know* the SE ones are setup for UK fuel and mine runs very nicely thank you.

Is this just the chip we're talking about here?

 

I know you need to have the ECU socketted to take a replacement chip, but is there anything other than the chip that can be changed?

 

I'm also seriously considering a new chip to replace my superchip (spits to the side in disgust!), but I can't find any info on the pro's and cons of the various options. SE's seem like a good idea, especially if you live close enough to SE Nissan (which I don't). I know the JWT's are very popular, but I'm even further away from them!

 

And is there anywhere in the North that can map a chip to suit the car's setup and get the best from all the parts?

Super chip! Get rid very soon.

SE do 'standard' chips which would be appropriate for a given car setup. Basic model is just exhaust and intake + boost upgrade, just like JWT. Only as you already the the ECU socketed then it'll be a damn sight cheaper.

How much is the SE chip?

 

Any one know?

£125;)

I was going to get a Blitz as it comes all fitted and exchange but they don't offer upgrades for turbos, injectors etc. just exhaust and air filter. Also the price put me off a bit at I think about £500.

Is that the pukker item direct from SE?

 

Sounds worth a look - there are plenty of copies about but I'm not sure if I need to be nervous about these or not.

 

And my car has exhaust, induction and boost upgrade (with bleed valves at present), I intend to add a boost controller soon and replace the chip at the same time.

 

So how do I choose between an SE and a JWT and where does the Mines fit into the running order?

MINES fits in the top of the running order but at about £800 very expensive and you can really only run it on optimax

I think SE quote 'from' £125, but that may be the basic cost, more will be if it is custom mapped.

 

See the attachment below for how you choose between JWT and SE. Done with my car on the same dyno, same day, runs a couple of minutes apart, car setup is very similar to yours by the sound of it, had an auto box at the time though.

 

Don't have a direct comparision for the MINES or any others, BUT AFAIK all Jap chips will be mapped for their 100RON fuel, Optimax is 98.5, mine runs on std unleaded, 95RON.

That's a suprising difference between the the 2 chips especially as the JWT has such a good reputation!

I personally like the idea of everything not being pushed to the max. Do SE leave a safety margin or is that the max for your setup?

it would definataly be more agressive, JWT build alot of saftey into there ECUS. I think a great way of doing this is to go for JWT and then get a super AFC and adjust from there, you can at least then have a reputable dealer with alot of history and back up if there are problems.

Then leave it standard - you don't get something for nothing.

IMO JWT run far too rich, but there again SE are also a little rich for safety. But as Waz says, you are free to alter this yourself (!) with an AFC if you want to live dangerously.

Gosh, and here was me thinking that this was confusing!

 

So there's more BHP from an SE chip according to the dyno printout, but some of you are worried about the safety factor?

 

and then there's someone suggesting that a mines chip is the ultimate ? what's so good about one of those and, presuming an AFC is the hook-up to fine tune a chip when it's in (?) does anyone know anybody up 'ere in the North West who does that?

 

(not the first time I've asked that, but so far it seems there are only a few keen forum members who have tried DIY chip tweeks, so there goes the 'reputable supplier' hang-up!)

 

Argh!

 

I think we all want the same thing - a nice reliable chip that is set to get good BHP without carving up the engine, and that can support a few mods (well that's what I want anyway).

 

and I'm as confused as ever!

:confused:

I guess I'm now sorry I asked. Time for some rolling road time, I think.

 

Bill

I'm going to get an EPROM emulator soon so I can map mine live on a rolling road, should be able to get v. good results, but takes ages to get spot on as you really need to map all the load/rpm sites and that's 16x16 for both fuel and timing.

Also need to find a RR shop that's got a good dyno road so you can hold the revs and map through the load sites, and a wide band lambda setup to keep a good eye on mixture. Some of the AFR's in the JWT go to 10:1 which is mega rich.

I've leaned mine out to 11.2:1 max, and had no problems at all. 12.6:1 should give the best power in theory, but didn't want to go that far yet as the timing may be off for mixture that lean.

If anyone's interested, SE will be doing me a switchable 2-map EPROM for standard and optimax. I'll be running 555's, forged pistons, 2 bar, bigger cams, blah, blah, blah... so when I get some plots I'll post them up. Only if they're look good tho.

HI Bill,

 

my Zed is going into zedworld on Monday to have the ECU remapped - i think jeff uses his own specifiactions - if you like i can give you a feel of before and after.

 

I think Jeff claims 70 bhp - i'm sure if you ask him he'll give you the specs.

 

regs,

 

alex

 

p.s. check with your insurance company - mine is charging me an extra £100 just because of the remapping

My insurance doubled for a chipped and modded car (now insured for up to +100BHP over standard though :D )

So one could upgrade ECU using the SE chip - (I presume thats the place in Essex which does alot of work on ZXs), all for £125 + fitting etc.

I know its been on the forum before but please clarify - if I've put on new exhaust decatted + blitz induct. + chipped, will the standard pistons, cam., turbos, autobox etc. cope with all this extra power.

I think I remember some post on the standard stuff coping with 400BHP.

 

Please clarify.

 

Geoff.

Correct me if I'm wrong but, with Zorst, decat, induction and chip you are only looking at 330 ish BHP.

 

If you up the boost with the chip this will bring you closer to the 400 bhp mark.

 

Should need to change anything else unless you wanna push more than say 13 - 14 psi of boost.

I could have the wrong end of the stick, but wasn't the conversation more like: standard turbos were good for up to 400 bhp? I can't see just those mods making that much power.

 

I'm probably wrong.

I have heard 14.7:1 is the A/F ratio Mecca, EGT's Detonation, engine design permitting?

Hi Guys,

 

 

Do a search using *ecu*, analyse all the information and make a decision!

 

 

SE chip you get more BHP but you take more of a risk with your engine!

 

JWT not as much BHP, but you get more fuel economy and engine longevity!

 

Jap chips are more designed for higher octane fuel!

 

Home made chips, crinkly or low fat take your pick!

 

Copied chips naughty but nice!

 

Zemulator Emanage or AFC great if you know what you are doing?

 

If you can't afford an engine rebuild go with JWT?
