Chips - and not just for Turbos

A few weeks ago there was some disussion on Titanic about an eBay auction of a chip for an S2 claiming +15bhp and +17lbft. The guy who's S2 is featured in 911&PW this month contacted the seller and found that he maps his own chips and can provide one for any 944 from (I think) 85.5 on - the guy actually has an '88 944 (either S or 2.7) of his own. One was fitted to the S2 in the mag and the results were reported to be good - increased smoothness and low rev flexiblity for example.

Anyhow a deal was offered to Titanic listers on the S2 chip - £47 all in - and I mailed to get one. It turned out that my ECU number was different, presumably because my cab is such a late 944. The chip from eBay was for an ECU ending in 153 (I think) and mine ended in 459. I can't spare the ECU to send off to be reverse engineered and mailed the guy to tell him so. He replied that he had the code for the 459 ECU but had never found a car to test it on.

Anyhow we agreed that I would test it and Richard duly sent me a pack containing 2 chips packed in a DAT tape box along with a plot of his map against standard, full fitting instructions, two disposable anti-static wrist bands, return postage labels and even a £2 coin to cover return postage if I didn't want the chips. If I did want one I was to send the other back along with a cheque for only £25 for testing them.

Because of work and my own supidity it was Monday before I collected the package from the Post Office and yesterday before I had the time to play with it. With the car running on BP Ultimate I warmed it up and drove it standard, paying attention to how it responded in different gears at different points in the rev range and varying throttle openings. When I was finished I opened my ECU to find a Superchip in there already.

I went ahead and took out my Superchip (sold for £293, apparently) and fitted Richard's BlitzChip 1. The car started just the same and settled into a perfect idle so I drove off. Very little difference from the Superchip, possibly a bit more eager at the top end. I then tried BlitzChip 2 which was indistinguishable. It turns out the map is the same but Richard thought one of the two just plain wouldn't work because of some setting in the software, but I didn't know that at the time.

I then went back to Chip 1 and then the Superchip. I have to say there is so little difference between these that even back to back it's difficult to tell the difference. Richard tells me he adds more fuel at the top and advances the ignition a little bit more, and I guess I can believe that. Apparently Superchips don't ever touch the fuelling when they remap.

Anyhow I am going to run a BlitzChip this week just to make sure I'm happy and then offer the Superchip on eBay. If you see it, don't waste your money bidding on it as it will be starting higher than you can get a chip that's just as good from Richard.

I'm in no way affiliated with BlitzChips, but I'm very impressed with the way Richard does business and the performance of his product - just as good as what Superchips charge £293 for and it's under £50. 8V chips are even less, and he has a set for the 220 Turbo as well. Should anyone want to get a chip Richard is on EECTuner@aol.com - tell him you got his details from me and he should do you the Titanic discount. I think he also does requests like raise the rev limit etc.

Hiya Fen

Excellent write up.

I bought a chip from Richard via eBay a few weeks back, as it was a bargain for £50, but have yet to fit it. I did have a look last weekend but couldn't split the boards on the ECU and didn't want to apply too much force just in case. I mailed Richard for advice and he mailed me some tips, pics etc so I should be putting it in this weekend.

My board was slightly different to the instructions (I think) in that the top 1 of the 3 rows of pins in the big connector are attached directly to the top board of my ECU and the bottom 2 rows are attached to the bottom board. I assumed that was because mine is a later ECU number because it looks like the ECU in the pictures has all the pins attached to the bottom board.

If your's is like that too then it's easy when you know how...

There are a couple of thin tabs at either end of the top row of pins. Pop them inwards and then gently lever between the top of the piece with the pins in and the outer edge of the connector, it should drop down easily if you have released the 2 tabs, then the board is free to come out.

If your connector doesn't have a separate row of pins across the top then disregard all of that [8D]
 
Seen one on e-bay for s2. Tempted. Will I notice any difference? Also, is this an inform insurance thing? I'm with Privilege at the moment.
 
From the Titanic post you would notice a difference. I'm thinking the BlitzChip is slightly peppier than my Superchip was after a day using it.

With the Superchip I could keep up with a 968 ClubSport (almost anyway, over about 1 mile and 50-130mph he pulled out about 2 car lengths) and then I started to use Optimax or BP Ultimate and that made a big difference to smoothness and lower revs flexibility.

Of course you should tell your insurer about all modifications, even though all chips look the same and the sticker 'fell off' mine...

The Titanic deal is £47 all-in, eBay is £49 + £3.25 postage IIRC.

i'm slightly confused about all this... what is the difference between me having one of these chips plus my Boost Enhancer, or buying a GURU 1/1a kit? I can see that the kit includes a fuel-pressure regulator; do i need to buy one of those? I'm also interested in what difference this will make when I come to do further upgrades (wastegate etc.). Speaking of which, what order should I be doing these upgrades in? Any general advice is most welcome! I'd rather pay a bit more for something that will be better... but obviously I'm keen to save money too [:)]

Your keen to save money eh!!! Well dont do any upgrades, keep the car standard and enjoy it. Use the money for track days..

Sound and sensible advice Slim, but I do like to spend money as well! [:D].
Having driven 13k miles all over Europe in the Turbo during the last 8 months I am looking to carry out a few upgrades in the coming months - brakes and exhaust are first, but after that I suppose anything goes really as long as i'm getting value for money (and lots of fun). Definitely want to do things gradually though, to get maximum enjoyment from each upgrade.
 
I imagine (But do not have any details of the blitz chips) that the guru chips are mapped for higher boost, more power. The FPR is to supply extra fuel to stop you leaning out at high RPM (bad). If the chips are not mapped for the FPR and you install one then you will run too rich (also bad).

The standard wastegate is a weak point in that it lets boost escape prematurely costing flexibility at lower rpms and power at higher rpms. The FPR upgrade will be required if you want to run much higher than standard boost and then you will need chips to match it.

Ideally once you have added all the bits you want a custom re-map would be the ultimate solution, giving the perfect fuelling /ignition for your car. (all of the shelf chips are a best guess). Unfortunately this will cost 350 to 500 pounds, (rolling road time plus an expert such as Wayne from chipwizards). I guess you could offset this a bit by selling your Guru (or whoever chips). Alternatively you could have a standalone engine management system and re-programme it yourself. but I believe this will cost in the region of £2k and requires a certain level of knowledge on ignition/fuelling/boost.

Thanks Tony; so would the following staged approach make sense:

a) Get a 'BlitzChip' for some instant fun
b) Upgrade dump valve, renew vacuum lines (do I need the FPR at this point?)
c) Upgrade wastegate
d) Custom remap

Oh, and at which point above does my dashboard boost gauge become redundant?

I did it this way, might not be the best but it worked for me...

Car
Boost gauge + A/F meter
Accuboost boost enhancer
Guru v9 chip + wastegate shims + 3.0 bar FPR
Exhaust and deCAT
I have been runnig at about 16psi and droping to 12 above 5000rpm
Hence wastegate on order...

If you adjust the boost then you need to adjust the fueling for the car. The standard FPR limits the fuel flow the 3.0bar one lets you max out the standard injectors for about 320-330bhp MAX.

I am no expert but if you pop a chip in it will have to be either a very mild remap of it will run lean (NOT good)

Value for money you just cant beat the guru stuff.

The dash boost only runs to 14.5psi. I got a VDO boost gauge which shows vacuum and up to 25psi boost (ample in other words)

You should definatly get an after market boost gauge (its very easy to install)
 
Not sure how much better than standard a blitz chip would be - might be similar to an S2, a bit smoother and a little bit more top end.

You shouldn't need an FPR untill you run more than standard boost, dump valve doesn't affect that wastegate can or not.

your list is an option but I did similar to slim so obviously that was my choice.

boost enhancer (brakes and shocks)

uprated turbo - as add on to rebuild

Boost gauge / air fuel guage
then guru chips /wastegate shims/fpr/reliaboost (not strictly required as boost enhancer does similar job)

Vacuum lines

wastegate next. (also waiting for 968 CS anti roll bars delivery soon)

Then probably MAP sensor of some type

custom re-map (maybe depending how its running on guru chips which danno can customise further)

I finally got round to swapping out my chip for the Blitzchip this weekend. I've not had time to have a good drive out yet but it actually ticks over more evenly

One question though "" how do I tell if the chip in my ECU was standard?

Here's a pic of it for all you experts out there.

You can't tell by looking at it, and stickers can be changed.

The only way is to read the contents and compare with the original chips. From there you can workout the changes (map, baseline settings, rev limit etc.) if you have the correct information or a specific DME programming software module.

Rick.

I appreciate what you're saying Rick, I just meant does it look like the standard chip expected in this ECU.

I don't suppose it really matters anyway [8D] I was just curious if the car was standard prior to me getting it

Andy
 
Not quite sure, Andy, but I seem to remember mine having 944 part number on the sticker ...

Come on you GURU upgraders, tell us whats on the chips you took out [:)][:)]

Just had a look on you web site. Nice Fords !! Have you still got the V8 RS2000 ??? looks my sort of car [:D][:D][:D]
 
Certainly have still got the V8 Rick.

I'm off down to start putting all of the new shiny bits into the engine tonight - cam kit, rings, shells, bearings, valves, springs, new ported heads etc. etc.
 
Well all I can say is cheers to Richard at Blitzchips.

I drove down from Middlesbrough to Birmingham yesterday and the car is running beautifully since putting the chip in.

Prior to fitting it, the car had a distinct powerband starting at 4,000rpm (or possibly a flat spot prior to 4,000) but now the power delivery is totally linear pulling from 3,000 all the way to the top [:D] I am well pleased and for £50 this has got to be the best value for money mod there is.

Nice one Richard :ROFLMAO:

I'll confirm the comparative MPG figures when I get home on Thursday. With the standard chip the car was delivering 30 - 35 mpg and judging by the fuel guage it should be similar but we shall see.

Andy
 
Another good result for the Blitzchip [:D] I am definitely going to stick one of these in the S2 before we have our rolling road day at Jamsport and I'll post the afterwards figure (compared to the 207bhp before)
