Hey Mike, have you tuned and mapped more fuel into the fuel tables to cope with more boost? Did you have any problems with maxing out (static) the injectors, or where they already big enough to cope?

well... i added no fuel via the tables as it's set to fuel at 12.0 AFR at loads above 0.8 (ie on boost) and 14.6AFR up until that point.  When it produces boost the MAF sees the air and fuels it accordingly.  Ive fitted 42lb injectors so they should be up to the job.

Its very easy to map, al you have to do is make sure the maf is correct, it then measures the air coming in and the ecu fuels to match.....

allegedly......

Ahhh you have a MAF rather than a MAP sensor. MAFs measure actual amount of air entering the engine, that's how it can compensate. I've got to work with a MAP sensor, which only measures pressure, or engine load, not actual airflow...

oh... that makes life a lot more complicated.. can you convert to a MAF setup like on the fox body mustangs ?

Nawww, I'm just gonna tune it with a wideband o2 and alter the fuel tables

happy days !!!

I did that at uni.. fairly easy depending on what you're tuning with, can you get a pot. box for your ecu?

The 'Ostrich' emulator that made you giggle is the toy to use. It's has a USB lead out of one end, and a ribbon cable out of the other, which has the pins on the end to pretend to be a EEPROM. The '7747 ECU in an 80's GM reads the spark and fuel tables from the EEPROM, which is why without an emulator you have to burn a new chip to make any changes. With the Ostrich, you just use TunerPro to upload immediate changes to the emulator over USB, which looks to the ECU like all the values have just changed, as it reads them constantly. Voila, on-th-fly tuning.

yup... that's the stuff... on the fly tuning is great but can be tricky on a rolling road, you could really do with an engine dyno, its far more controlled

The Ostrich is supposed to be the business.

And the old GM MAF sensor is 8 bit and can't read much airflow.  The airflow for 390BHP (iirc) or so is about the limit of its ability.

so.....

i ordered the idler pulley for it today, we'll have to wait for that to show up before I can fiddle with it any more.

pulley shipped out of Texas last night.... lets see how long USPS and Parcel Farce take to get it to me

well....

i finally got the pulley and then blower re-installed tonigt, started the car up and again it's making the same noise.

So i got on the blower to paxton, a different tech support guy watched the video and said "yeah, that's fine" !!!!

So the general theory is, i'll put a couple of hundered miles on it and see what its like, if there's any problems i'll try sendoing it back, but for now...

MOT... Mapping... Enjoying....

Expensive, yet supprisingly happy days :)

Mikeyboy, gonna have to meet up soon, I seem to be going down the same path as you!! I'm waiting for an ebay ordered puller to turn up so I can slap on the serpentine conversion pulley onto the power steering pump (which also powers the brakes!), abd then it's mapping time too...

MOT is booked for Saturday 19th... Guess I better get the wideband O2 sensor out of the exhaust bung to stop it catching on the driveway... (here merely as a note to self)

Just trying to figure out how much mapping i can do on the road and how little dyno time I can get away with... at £95/hour it's not cheap !!!!

I can probably do most of the part throttle mapping on a lap around the M25, and if I stop off at service stations along the way I can use the on ramps to do a bit of full throttle on boost mapping..... only in the dry though... Im not planning another full throttle boost enhanced pendulum swing like last time in the wet !!!

Does anyone have a good set of det' cans I could borrow for a few days ???

oh... and Paxton said the blower is fine... thats just the noise it makes when new, the bearings need to bed in apparently...... not convinced but .... ok...
